1 1 Introduction

The HT32 Starter Kit is based around the 32-bit Arm® Cortex®-M0+/M3 high performance microcontroller and is designed to assist users to get up and running with the Holtek 32-bit device range as quickly as possible.

Standard C language programs can be developed using the integrated development environment from Keil μVision and IAR EWARM. Using this foundation, Holtek also provides a comprehensive function library to avoid complicated lower level function development in order to allow designers to focus their time on their specific application development. Using a simple USB cable connection, users only have to connect their PC to the integrated hardware debug interface (e-Link32 Lite Serial-Wire Debugger) to automatically download the programs and immediately commence debug operations.

e-Link32 Lite Power Option – R8R8 Description

Pin 1 on the CN2 connector on the e-Link32 Lite side is used as the input. The reference voltage is supplied through this pin to the voltage conversion chip – default settingNote that if the e-Link32 Lite has not been separated, the 3.3V on the Target Board will have been connected to CN2-1 through the PCB wire connectionPin 1 on the CN2 connector on the e-Link32 Lite side is used as the output. Here the e-Link32 Lite voltage conversion chip is fixed using 3.3V as the reference voltage. Note that the 3.3V voltage on the Target Board has been connected to CN2-1 through the PCB wire connection, therefore this option is not allowed if the e-Link32 Lite has not been separated

Only the e-Link32 Lite V2.0 version has the R8 option.

e-Link32 Lite Power Option – J8J8 Description

Pin 1 on the CN2 connector on the e-Link32 Lite side is used as the input. The reference voltage is supplied through this pin to the voltage conversion chip – default settingNote that if the e-Link32 Lite has not been separated, the 3.3V on the Target Board will be connected to CN2-1 through the S1 switch and the PCB wire connectionPin 1 of the CN2 connector on the e-Link32 Lite side is used as the output. Here the e-Link32 Lite voltage conversion chip is fixed using the 3.3V as the reference voltageNote that the 3.3V on the Target Board will be connected to CN2-1 through the S1 switch and the PCB wire connection. If the e-Link32 Lite has not been separated, users should switch the S1 to the OFF position to use this option

Only the e-Link32 Lite V2.2 or V2.3 version has the J8 option.

Boot Option – Located on the Board Reverse SideR18 Description

1 or NC – MCU boots from main flash – default setting

0 – MCU boots from bootloader – ISP

High Speed External Crystal Oscillator (HSE) Option R23 & R24 Description

Open, HSE I/O pins disconnected from CN4 – default setting

Short, HSE I/O pins connected to CN4 pins 9 and 10. Y2 must be removed.

The designators on the ESK32-30105 (HT32F12366 SK) are R21 and R22.

Short, USB D+/D- pins connected to the CN4 pins 55 and 56.

The early Starter Kit board or its Target MCU does not have an integrated USB or its USB D+/D- are not bonded with the GPIO, therefore this option is not available.

MCU Power Jumper – J1J1 Description

The MCU VDD pin is connected to the 3.3V power – default setting

The MCU VDD pin is disconnected from the 3.3V power

The jumper is useful when it is required to measure the MCU power consumption.

UART Option Jumper – J2The Starter Kit arranges a group of the Target MCU UART to be used as external communication interfaces, which can connect to the host computer or other devices. The Target MCU RX pin has the option of connecting to the e-Link32 UART TX pin or to the extension connector, CN4_6: RS232_TX.

4 Schematics

The diagrams above are the schematic diagram of the connection between the e-Link32 Lite and the Target Board:

▆ The e-Link32 Lite currently uses three hardware versions which are V2.0, V2.2 and V2.3. Because V2.2 and V2.3 are roughly the same, only V2.3 is listed here. The detailed schematic diagram will be attached to the schematic section for reference.

▆ The U4, U5 and U6 level shifter ICs are responsible for converting the SWDIO and SWCLK pin voltage levels to the Target MCU voltage level. When J8 or R8 is selected to be open circuit, CN2-1 is used as an input and the e-Link32 Lite is separated, the reference voltage must be supplied on CN2-1.

▆ J8 or R8 can determine whether VDD_elink32 and CN2-1 are connected together. If they are connected together, the SWDIO and SWCLK pin higher levels are fixed at 3.3V. At the same time CN2-1 has the ability to output 3.3V, which can be supplied to the user’s own board.Here it should be noted that if the user’s own board contains a power supply, then CN2-1 cannot be connected to the user’s own board, otherwise it may cause a power conflict.

▆ CN2 and CN6 are the SWD connectors of the e-Link32 Lite and the Target Board respectively. ● If the e-Link32 Lite is not separated, there is already a PCB line connection on the board, so

switching S1 to the ON position can connect the Target Board without an additional flying line connection.

● If the e-Link32 Lite is not separated and S1 is switched to the OFF position, CN2 can be connected to the user’s own board through a flying line.

● When the e-Link32 Lite is separated, CN2 can be connected to the Target Board CN6 or the user’s own board through a flying line.

▆ The e-Link32 Lite has an integrated USB to UART function which is called the “Virtual COM Port”, CN8 is its UART side connector. ● If the e-Link32 Lite is not separated, users can use the e-Link32 “Virtual COM Port” functions

by connecting J2 to DAP_TX. ● If the e-Link32 Lite is not separated, and users wish to connect the e-Link32 RX to their

board, they need to erase the Target MCU of the Starter Kit to avoid conflict. ● When the e-Link32 Lite is separated, CN8 can be connected to the Target Board or the user’s

own board through a flying line.

1uF (or 2.2uF) capacitor fromthe LDOOUT/CLDO to the VSS isrequired (close to MCU).

External pull up resistance of the nRST canbe changed to 10K for interference/noiserejection. The capacitor from the nRST toVSS can be NC if no button used.

The VBAT must connect to the VDDwhen no extra battery is used in thesystem (VBAT floating is not allowed). The BOOT pin must be maintained at high level when reset.

4.7K external pull up resistance may be required for the BOOTpin (for interference/noise rejection and rising time during thereset).
