PRELIMINARY PRODUCT INFORMATION
MOS INTEGRATED CIRCUIT
µPD78F0066
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The µPD78F0066 is a product of the µPD780065 Subseries in the 78K/0 Series. It is equivalent to the
µPD780065 with a flash memory in place of internal ROM^Note. Because this device can be written and erased
electrically without being removed from the substrate, it is ideally suited for evaluation at system development,
small-scale production, and for systems likely to be upgraded frequently.
Note The internal ROM capacity is different (refer to 1. DIFFERENCES BETWEEN µPD78F0066 AND MASK
ROM VERSIONS for details).
Functions are described in detail in the following user’s manuals, which should be read when carrying
out design work.
µPD780065 Subseries User’s Manual : Under preparation
78K/0 Series User’s Manual Instruction : U12326E
FEATURES
• Pin-compatible with mask ROM versions (except VPP pin)
• Flash memory
: 48 Kbytes^Note
• Internal high-speed RAM : 1024 bytes
• Internal expansion RAM : 4096 bytes
• Buffer RAM
: 32 bytes
• Operable with the same power supply voltage as that of mask ROM version (VDD = 2.7 to 5.5 V)
Note The flash memory capacity can be changed with the memory size switching register (IMS).
Remark For the differences between the flash memory versions and the mask ROM versions, refer to 1.
