MOS INTEGRATED CIRCUIT

µPD78P048A

8-BIT SINGLE-CHIP MICROCONTROLLER

DESCRIPTION

The

µPD78P048A is a product in the µPD78044F subseries within the 78K/0 series, in which the internal ROM

of the

µPD78042F, 78043F, 78044F, and 78045F is replaced with one-time PROM or EPROM.

As the

µPD78P048A is user-programmable, it is ideal for evaluation in system development, short-run and multiple-

device production, and early start-up.

Details of functions are described in the User's Manuals shown below. Be sure to read in design.

µPD78044F subseries User's Manual: U10908E

78K/0 series User's Manual -Instruction: U12326E

FEATURES

•

Pin compatible with mask ROM products (except the VPP pin)

•

Internal PROM: 60K bytesNote 1

•

Internal high-speed RAM: 1024 bytesNote 1

•

Internal expansion RAM: 1024 bytesNote 2

•

Buffer RAM: 64 bytes

•

FIPTM display RAM: 48 bytes

•

Operable in the same supply voltage as mask ROM products: VDD = 2.7 to 6.0 V (except A/D converter)

A/D converter supply voltage: AVDD = 4.0 to 6.0

Notes 1.

Internal PROM and internal high-speed RAM capacities can be changed by memory size switch-

ing register (IMS).

Internal expansion RAM capacity can be changed by internal expansion RAM size switching
