MOS INTEGRATED CIRCUIT

PD178F098

8-BIT SINGLE-CHIP MICROCONTROLLER

DESCRIPTION

The

PD178F098 is a flash memory model of the

PD178076, 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:

PD178078, 178098 Subseries User’s Manual: U12790E

78K/0 Series User’s Manual - Instruction

: U12326E

FEATURES

• Serial interface (UART mode)

• IEBus

controller

• Pin-compatible with mask ROM models (except V

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 (V

= 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

PD178F098 AND MASK ROM MODELS.

The electrical specifications (such as supply current) in the

PD178F098 differ from those of the

mask ROM models. Confirm these differences before mass-producing any application set.

APPLICATION FIELD

Car stereos
