GDC21D601

32-Bit RISC MCU

Hynix Semiconductor 

• Real Time Clock

- 32bit counter clocked by a 32.768KHz clock.

- 32bit match register

• Programmable Input Output

- up to 80 pin (8bit 10channel)

- Each pin can be configurable as either input or

output

• Timer

- 6 channel 16-bit up-count

- 4-internal pre-scaleable , 4-external input clock

. 1 interrupt per 1 channel

. 2 inout pin per 1 channel for input capture or

output compare

- Basic function :

. Compare match waveform output

. Input capture

. Match clear

. Capture clear

- Synchronous mode

. Synch. clear at two or more channel

. Synch. write at two or more channel

- PWM waveform output mode

• Synchronous Serial Interface

- Supports full duplex communication

- Sends and receives data continuously, using 16 x

8 bit FIFOs

- Built-in baud rate generator capable of

generation 4 clock rate

- Selectable clock source : either built-in buad-rate

generator or external clock

- 4 independent interrupts : transmit-end, rx-full,

tx-empty and tx-full

GDC21D601

• UART

- 2 channel : UART only

. Compatible with 16550

. 16 byte each FIFO for TX / RX

. Start, stop and parity bit can be added or

deleted from/to serial data

. MODEM control functions (CTS, RTS, DSR,

DTR, RI and DCD )

. Fully programmable serial-interface

characteristics

: 5-, 6-, 7- or 8-bit characters

: even, odd or no-parity bit generation and

detection

: 1-, 1.5- or 2-stop bit generation and

detection

• SmartCard Interface

- 1 channel : Support SmartCard Interface

. Supports only asynchronous operation

. Supports cards that have internal reset

capability

. Supports cards that have an active low reset

input

. Supports cards that use the internal clock

. Generate the clock for a card expecting the

external clock

. Use the serial in/out ports for I/O

. Use the PIO ports for other interface signals

like RST, DETECT, etc

• I2C

- 3 channels

- Master / Slave function

- Programmable clock speed

- 8bit data transfer

- Slave clock stretch support

- Maskable interrupt

- Support clock rates up to 1.84MHz Baud
