Note The internal flash memory, internal high-speed RAM capacities, and internal expansion RAM capacities

can be changed using the internal memory size switching register (IMS) and the internal expansion RAM

size switching register (IXS). For IMS and IXS, see 27.1 Memory Size Switching Register and 27.2

Internal Expansion RAM Size Switching Register.

{ Buffer RAM: 32 bytes (can be used for transfer in CSI with automatic transmission/reception function)

{ On-chip single-power-supply flash memory

{ Self-programming (with boot swap function)

{ On-chip debug function (µPD78F0547D only)Note

{ On-chip power-on-clear (POC) circuit and low-voltage detector (LVI)

{ On-chip watchdog timer (operable with the on-chip internal low-speed oscillation clock)

{ On-chip multiplier/divider (16 bits × 16 bits, 32 bits / 16 bits)

{ On-chip key interrupt function

{ On-chip clock output/buzzer output controller

{ I/O ports: 71 (N-ch open drain: 4)

{ Timer: 8 channels

• 16-bit timer/event counter: 2 channels

• 8-bit timer/event counter: 2 channels

• 8-bit timer:

2 channels

• Watch timer:

1 channel

• Watchdog timer:

1 channel

Note The µPD78F0547D has an on-chip debug function. Do not use this product for mass production because its

reliability cannot be guaranteed after the on-chip debug function has been used, from the viewpoint of the

restriction on the number of times the flash memory can be rewritten. NEC Electronics does not accept any

complaint about this product.
