What are the key features of PIC16C923-04/PT?
- 8-bit PIC16 OTP core at up to 4 MHz with integrated LCD segment driver, eliminating external display controller ICs
- On-chip USART serial interface enables direct RS-232 or RS-485 communication without glue logic
- QFP surface-mount package with 64 or 68 pins provides ample I/O for LCD, keypad, and sensor interfaces in a single chip
What is PIC16C923-04/PT used for?
The PIC16C923 targets legacy consumer appliances, utility meters, and industrial panel displays that require an integrated LCD driver alongside general-purpose microcontroller functions at 4 MHz clock speed. Its OTP (one-time programmable) memory architecture is favored for high-volume production where firmware is locked at programming time, minimizing per-unit programming costs. Replacement boards for older instrumentation and security-panel controllers also use this device for backwards-compatible firmware deployments.

Frequently Asked Questions
What clock frequency does the PIC16C923 support, and what does that mean for simple display-control tasks?
The PIC16C923 runs at up to 4 MHz, delivering 1 MIPS throughput. For an LCD refresh loop updating 32 segments at 60 Hz, that budget provides approximately 16,000 instruction cycles between refresh events — more than sufficient for scan, decode, and GPIO toggling in a 4-digit numeric display application.
Why does the OTP memory architecture of the PIC16C923 benefit high-volume production over flash-based alternatives?
OTP memory is programmed once during manufacturing and cannot be altered, preventing accidental firmware overwrites in the field. For production runs above 10,000 units, OTP devices cost 15–30% less per unit than equivalent flash-based MCUs and require no read-back verification step, reducing per-board programming time by 3–5 seconds.
How does the integrated LCD driver in the PIC16C923 reduce external component count versus a standalone MCU?
The PIC16C923 integrates a static or 1/2, 1/3, or 1/4 multiplex LCD driver supporting up to 4 × 23 = 92 segments, removing the need for a separate LCD controller IC and level-shift resistors. This reduces BOM cost by 2–4 components and saves up to 200 mm² of board area compared to an external driver like the HT1621.
For a meter replacement PCB, how does the QFP package of the PIC16C923 compare to a DIP alternative?
The PIC16C923 in a 64-pin QFP (10 mm × 10 mm, 0.5 mm pitch) occupies roughly 100 mm² versus approximately 900 mm² for a 64-pin ceramic DIP, allowing a 9× reduction in processor footprint. This space saving is critical when replacing legacy DIP boards with compact SMT designs in panel-meter enclosures.
