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)
• IEBus^TM controller
• Pin-compatible with mask ROM models (except VPP pin)
• Flash memory: 60K bytes^Note
• Internal high-speed RAM: 1024 bytes
• Internal extension RAM: 2048 bytes^Note
• 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.
