High Speed 16-Bit Microcontroller
1. Features
Five-stages pipeline
RISC architecture
Integrated PLL(*1~*8)
Maximum frequency is 80 MHz; External bus, Internal bus and core are in the same clock base
Bus interface
- Multiplexed address and Data bus
- Supports direct address bus [A19 : A0]
- 8-bit or 16-bit external bus dynamic access
- 1M byte memory address space
- 64K byte I/O space
Software is compatible with generic 80C186 microprocessor
Support two Asynchronous serial channels with hardware handshaking signals.
External bus, Internal bus and core are in the same clock base
Supports 32 PIO pins
Three independent 16-bit timers and one independent programmable watchdog timer
The Interrupt controller with seven maskable external interrupts and one non-maskable external interrupt(NMI)
Two independent DMA channels
Programmable chip-select logic for Memory or I/O bus cycle decoder
Programmable wait-state generator
The I/O pin output is 3.3 volt level and the input is 3.3 volt to 5 volt tolerance.
3.3V operation voltage
