MOS INTEGRATED CIRCUIT
µPD75P218
4-BIT SINGLE-CHIP MICROCOMPUTER
The µPD75P218 is a one-time PROM version that can be written to only once or an EPROM version that allows
program writing, erasing, and rewriting, of the µPD75218 Note.
Since the program can be written by the user, the µPD75P218 is suitable for preproduction use during
system development, or limited production.
Read this material together with the µPD75218 materials.
Note Under development
FEATURES
• µPD75218 compatible
• On-chip 16K-byte mode/32K-byte mode switching function
• Operates at the same power supply voltage range (2.7 to 6.0 V) as the mask ROM version µPD75218.
• 32640 × 8 bits of PROM
• 1024 × 4 bits of RAM
• No pull-down resistor for Port 6
• High breakdown voltage display output
• S0 to S8, T0 to T9 : On-chip pull-down resistor
• S9, T10 to T15 : Open drain
• No power-on reset circuit
Caution No mask-option pull-down resistor is provided.
