Overview

  • Pin compatible with mask ROM versions (except VPP pin)
  • Internal PROM: 32K bytesNote
  • µPD78P014DW : Reprogrammable (ideal for system evaluation)
  • µPD78P014CW, 78P014GC-AB8 : Programmable once only (ideal for small-scale production)
  • Internal high-speed RAM: 1024 bytesNote
  • Buffer RAM: 32 bytes
  • Operable over same supply voltage range as mask ROM version (2.7 to 6.0 V)
  • Available for the QTOPTM microcomputer Note The internal PROM and internal high-speed RAM size can be set by means of the memory size switching register. Remark The QTOP microcomputer is the general term for a single-chip microcomputer with on-chip one-time PROM. NEC supports its program writing, marking, screening, and verification. Differences from mask ROM versions are as follows:
  • The same memory mapping as on a mask ROM version is possible by setting the memory size switching register.
  • There is no function for incorporating pull-up resistors by means of a mask option in P60 to P63 pins.
