Description

The Cost-Effective A/D Flash Type MCU with EEPROM Devices are a series of 8-bit high performance RISC architecture microcontrollers, designed especially for applications that interface directly to analog signals, such as those from sensors. All devices include an integrated multi-channel Analog to Digital Converter in addition to one or two Pulse Width Modulation outputs.

Key Features

  • Operating voltage:
  • 4 channels 8 or 9-bit resolution A/D converter
  • 1 or 2 channel 8-bit PWM output shared with I/O lines
  • Bit manipulation instruction
  • 63 powerful instructions
  • All instructions executed in one or two machine fSYS=4MHz: 2.2V~5.5V fSYS=8MHz: 3.3V~5.5V fSYS=12MHz: 4.5V~5.5V
  • 13 to 23 bidirectional I/O lines
  • External interrupt input shared with an I/O line
  • 8-bit programmable Timer/Event Counter with over- flow interrupt and 7-stage prescaler
  • On-chip crystal and RC oscillator
