GDC21D601 Datasheet, PDF (10/189 Pages) Hynix Semiconductor – 32-Bit RISC MCU

• 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
