Overview
DATA SHEET MOS INTEGRATED CIRCUIT µPD178F098 8-BIT SINGLE-CHIP MICROCONTROLLER DESCRIPTION The µPD178F098 is a flash memory model of the µPD178076, 178078, 178096, and 178098, and is provided with a flash memory to/from which data can be written/erased with the microcontroller mounted on a printed circuit board.
For the detailed functional description, refer to the following User’s Manuals: µPD178078, 178098 Subseries User’s Manual: U12790E 78K/0 Series User’s Manual - Instruction : U12326E FEATURES • Serial interface (UART mode) • IEBusTM controller • Pin-compatible with mask ROM models (except VPP pin) • Flash memory: 60K bytesNote • Internal high-speed RAM: 1024 bytes • Internal extension RAM: 2048 bytesNote • Buffer RAM: 32 bytes • Operable at same supply voltage as mask ROM models (VDD = 4.
5 to 5.
5 V during PLL operation) Note The capacities of the flash memory and internal extension RAM can be changed using the memory size select register (IMS) and internal extension RAM size select register (IXS).
Remark For the differences between the flash memory model and mask ROM models, refer to 1.
DIFFERENCES BETWEEN µPD178F098 AND MASK ROM MODELS.
The electrical specifications (such as supply current) in the µPD178F098 differ from those of the mask ROM models.
Confirm these differences before mass-producing any application set.
