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.

Caution The µPD78P048AKL-S does not provide the reliability intended for mass production of user

systems. Use this model only for experiments and evaluation of functions.

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 bytes^{Note 1}

µPD78P048AKL-S: Reprogrammable. (ideal for system evaluation)

µPD78P048AGF-3B9: Programmable only once (ideal for limited production)

Internal high-speed RAM: 1024 bytes^{Note 1}

Internal expansion RAM: 1024 bytes^{Note 2}

Buffer RAM: 64 bytes

FIP^TMdisplay RAM: 48 bytes

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

A/D converter supply voltage: AV^DD= 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).

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

Remark For the difference between ROM products and mask ROM products, refer to 1. DIFFERENCES

BETWEEN µPD78P048A AND MASK ROM PRODUCTS.

In this document, “PROM” is used in parts common to one-time PROM products and EPROM products.

The information in this document is subject to change without notice.
