UPD78P0308 - NEC

UPD78P0308 8-BIT SINGLE-CHIP MICROCONTROLLER

The µPD78P0308 and 78P0308Y are members of the µPD780308 and 780308Y Subseries of the 78K/0 Series, in which the on-chip mask ROM of the µPD780308 and 780308Y is replaced with a one-time PROM. Because this device can be programmed by users, it is ideally suited for system evaluation, small-scale and multiple-device production, and early development and time-.

Features

• Pin-compatible with mask ROM version (except VPP pin)
• Program memory (one-time PROM): 60 KBNote
• Internal high-speed RAM:
• Internal expansion RAM:
• LCD display RAM:
• Supply voltage: 1024 bytes 1024 bytes 40 x 4 bits VDD = 2.0 to 5.5 V Note The internal PROM capacity can be changed by setting the internal memory size switching register (IMS). Remark Refer to 1.
