DATA SHEET
DESCRIPTION
The
μ
PD178F098 is a flash memory model of the
μ
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:
μ
PD178078, 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 V
PP
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
DD
= 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
μ
PD178F098 AND MASK ROM MODELS
.
The electrical specifications (such as supply current) in the
μ
PD178F098 differ from those of the
mask ROM models. Confirm these differences before mass-producing any application set.
