HMS77C2000/2001
8 PIN, 8-BIT CMOS SINGLE-CHIP MICROCONTROLLER
High-Performance RISC CPU:
- Only 33 single word instructions to learn
- All instructions are single cycle (1 us) except for
program branches which are two-cycle
- Operating speed: DC - 4 MHz clock input
DC - 1 us instruction cycle
- 12-bit wide instructions and 8-bit wide data path
- Seven special function hardware registers
- Two-level deep hardware stack
- Direct, indirect and relative addressing modes
for data and instructions
- Internal 4 MHz RC oscillator with programmable
calibration
- In-circuit serial programming
Peripheral Features:
- 8-bit real time clock/counter (TMR0) with 8-bit
programmable prescaler
- Power-On Reset (POR)
- Internal Reset Timer (IRT)
- Watchdog Timer (WDT) with its own on-chip RC
oscillator for reliable operation
- Programmable code-protection
- Noise immunity circuit: Power fail detector
- Power saving SLEEP mode
- Wake-up from SLEEP on pin change
- Internal weak pull-ups on I/O pins
- Internal pull-up on RESET pin
- Selectable oscillator options:
IRC: Internal 4 MHz RC oscillator
ERC: External low-cost RC oscillator
(200KHz ~ 4MHz)
XT: Standard crystal/resonator
(455KHz ~ 4MHz)
LF: Power saving, low frequency crystal
(32KHz ~ 200KHz)
