UPD754264 Product details

DESCRIPTION
The µPD754264 is a 4-bit single-chip microcontroller which incorporates the EEPROMTM for key-less entry application.
It incorporates a 32 × 8-bit EEPROM, a CPU performing operation, a 4-Kbyte mask ROM to store software, a 128 × 4-bit RAM to store the operation data, an 8-bit resolution A/D converter, and a carrier generator which easily outputs waveforms for infrared remote controller.
The details of functions are described in the following user’s manual. Be sure to read it before designing.

FEATURES
• On-chip EEPROM: 32 × 8 bits (mapped to the data memory)
• On-chip key return reset function for key-less entry
• On-chip low-voltage A/D converter (AVREF = 1.8 to 6.0 V), 8-bit resolution × 2 channels
• Low-voltage operation: VDD = 1.8 to 6.0 V
• Timer function (4 channels)
   • Basic interval timer/watchdog timer : 1 channel
   • 8-bit timer counter : 3 channels
• On-chip memory
   • Program memory (ROM)
      4096 × 8 bits
   • Data memory (static RAM)
      128 × 4 bits
• Instruction execution time variable function suited for high-speed operation and power saving.
   0.95, 1.91, 3.81, 15.3 µs (@ fX = 4.19-MHz operation)
   0.67, 1.33, 2.67, 10.7 µs (@ fX = 6.0-MHz operation)

APPLICATIONS
   Automotive appliances such as key-less entry, compact data carrier, etc.
