8-bit microprocessor with low-power and high-speed CMOS technology

Технічні параметри:

Operating voltage range: 2.3V~5.5V
Available in temperature range: 0°C~70°C
Operating frequency range (base on 2 clocks):
Crystal mode: DC~20MHz at 5V, DC~8MHz at 3V, DC~4MHz at 2.3V.
ERC mode: DC~4MHz at 5V, DC~4MHz at 3V, DC~4MHz at 2.3V.
Low power consumption:
less then 1.5 mA at 5V/4MHz
typical of 15 µA, at 3V/32KHz
typical of 1µA, during the sleep mode
1024 × 13 bits on chip ROM
Built-in calibrated IRC oscillators (8MHz, 4MHz, 1MHz, 455KHz )
Programmable prescaler of oscillator set-up time
One security register to prevent the code in the OTP memory from intruding
One configuration register to match the user’s requirements
32× 8 bits on chip registers (SRAM, general purpose register)
2 bi-directional I/O ports
5 level stacks for subroutine nesting
8-bit real time clock/counter (TCC) with selective signal sources and trigger edges, and with overflow interrupt
Power down mode (SLEEP mode)
Three available interruptions
TCC overflow interrupt
Input-port status changed interrupt (wake up from the sleep mode)
External interrupt
Programmable free running watchdog timer
7 programmable pull-high I/O pins
7 programmable open-drain I/O pins
6 programmable pull-down I/O pins
Two clocks per instruction cycle 
The transient point of system frequency between HXT and LXT is around 400KHz.
