UPD78F0988A

DATA SHEET MOS INTEGRATED CIRCUIT µPD78F0988A, 78F0988A(A) 8-BIT SINGLE-CHIP MICROCONTROLLERS DESCRIPTION The µPD78F0988A and 78F0988A(A) are products in the µPD780988 Subseries in the 78K/0 Series that have flash memory in the place of the internal ROM of the µPD780988. Flash memory can be written or erased electrically with the device mounted on the board. Therefore, the µPD78F0988A and µPD78F0988A(A) are ideal for evaluation in system development, small-scale production, or systems likely to be upgraded frequently. Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before designing. µPD780988 Subseries User’s Manual: U13029E 78K/0 Series Instruction User’s Manual: U12326E FEATURES Pin-compatible with mask ROM version (except VPP pin) Flash memory: 60 KBNote 1 Internal high-speed RAM: 1024 bytes Internal expansion RAM: 1024 bytesNote 2 Operable in the same supply voltage range as the mask ROM version (VDD = 4.0 to 5.5 V) Notes 1. The capacity of the flash memory can be changed with the internal memory size switching register (IMS). 2. The capacity of the internal expansion RAM can be changed with the internal expansion RAM size switching register (IXS). Remark For the differences between the flash memory versions and the mask ROM versions, refer to 1. DIFFERENCES BETWEEN µPD78F0988A AND MASK ROM VERSIONS.
