SN8F5907B is an 8-bit architecture microcontroller which compatible with MCS-51 instruction
set. It runs at up to 12.1 times faster than the original 8051 at the same frequency.
Meanwhile, its advanced semiconductor technology provides a wide range operation voltage,
from 1.8 V to 5.5 V, and working temperature between -40°C and 85°C at 32 MHz CPU
clock rate.
The microcontroller builds in a 64 KB flash memory (IROM), 256 bytes internal
RAM (IRAM) and 2 KB on-chip external RAM (XRAM). A hardware MDU dramatically improves
mathematical operations performance. Furthermore, a 9 input channels/24-bit resolution
ADC, One Programmable Gain Instrument Amplifier, 4*44 or 6*42 LCD driver (176~252
dots), One OP-Amps and comparator, one Regulator (AVDDR and ACM), three 16-Bit Timer/Counter
with Auto reload, PWM Output function, One 8-Bit base Timer for RTC , Communication
interfaces (UART, SPI, I2C) to fit in the vast majority of consumer electronics, Blood
Pressure、Thermometer Application and Medical Measurement Applications.
