UPD75P218 Datasheet 4-bit Single-chip Microcomputer

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD75P218 4-BIT SINGLE-CHIP MICROPUTER The µPD75P218 is a one-time PROM version that can be written to only once or an EPROM version that allows program writing, erasing, and rewriting, of the µPD75218 Note. Since the program can be written by the user, the µPD75P218 is suitable for preproduction use during system development, or limited production. Read this material together with the µPD75218 materials.

Key Features

  • µPD75218 compatible On-chip 16K-byte mode/32K-byte mode switching function Operates at the same power supply voltage range (2.7 to 6.0 V) as the mask ROM version µPD75218. 32640 × 8 bits of PROM 1024 × 4 bits of RAM No pull-down resistor for Port 6 High breakdown voltage display output.
  • S0 to S8, T0 to T9 : On-chip pull-down resistor.
  • S9, T10 to T15 : Open drain.
  • No power-on reset circuit Caution.
