What are the key features of PIC16C924/CL?
- 8-bit PIC core at up to 8 MHz with 7 KB one-time-programmable Flash, 176 bytes RAM, and 52 I/O lines for high pin-count embedded control in a 68-pin PLCC package
- Integrated LCD segment driver supporting direct multiplexed LCD panel drive, eliminating external LCD controller ICs in meter and appliance panel designs
- Multi-channel ADC for analog sensor acquisition combined with extensive I/O capacity, enabling mixed-signal human-interface and measurement applications in a single chip
What is PIC16C924/CL used for?
The PIC16C924/CL is designed for appliance control panels, industrial display-equipped controllers, and smart meter interfaces where an integrated LCD driver and 52 I/O lines must coexist in one device. Its 8 MHz PIC core handles both display multiplexing and analog sensor sampling, removing the need for a separate LCD controller in cost-sensitive consumer products. The 68-pin PLCC package suits through-hole or socket-mounted prototyping for legacy industrial equipment and low-to-medium volume production runs.

Frequently Asked Questions
What makes the PIC16C924/CL suitable for direct LCD panel driving without an external controller?
The PIC16C924/CL integrates an LCD segment driver that supports multiplexed panel configurations with up to 4 commons and multiple segment lines. This on-chip LCD module removes the cost and board area of a dedicated LCD controller IC, making it practical for 4-digit numeric or simple alphanumeric displays in utility meters and home appliances running from a 2 V to 6 V supply.
How does the 52-I/O line count of the PIC16C924/CL compare to typical 28-pin or 40-pin PIC devices for high pin-count applications?
With 52 I/O lines in a 68-pin PLCC package, the PIC16C924/CL provides roughly twice the GPIO of a 28-pin device and significantly more than a 40-pin DIP. This density allows it to simultaneously drive a multi-segment LCD, read a keypad matrix of 16 or more keys, and interface with 8-bit parallel peripheral buses without external I/O expanders.
At 8 MHz, how long does the PIC16C924/CL take to execute a single instruction cycle and what does that imply for real-time response?
The PIC16C924/CL executes most instructions in 1 instruction cycle, which equals 4 clock periods. At 8 MHz, one instruction cycle is 0.5 µs, giving a throughput of 2 million instructions per second. This is adequate for scanning a 4×4 keypad at 10 ms intervals, updating an LCD frame buffer, and running a simple PID loop at 100 Hz simultaneously.
Is the PIC16C924/CL appropriate for new designs or is a flash-based alternative recommended for production flexibility?
The PIC16C924/CL uses one-time-programmable (OTP) memory, meaning firmware cannot be reprogrammed after manufacturing. For new designs requiring firmware updates or field upgrades, Microchip recommends flash-based successors such as the PIC16F913 or PIC16F916, which offer 8 MHz operation with similar LCD driver peripherals and re-programmable 7 KB to 14 KB Flash in comparable 64-pin packages.
