PIC16C924-08/PT - 8MHz 8-Bit MCU w/ LCD Driver | Microchip
MPN: PIC16C924-08/PT ✓ فعالPIC16C924-08/PT جائزہ
A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory, working RAM, and a mix of peripheral blocks such as timers, A/D converters, communication interfaces, and I/O. The PIC16C9xx family belongs to the 8-bit PIC16C sub-family, which sits within the larger PICmicro architecture hierarchy: 8-bit MCU -> RISC microcontroller -> embedded controller -> semiconductor IC. The "C" suffix indicates an OTP (One-Time-Programmable) EPROM-based program memory variant intended for low-to-medium volume production where field re-programmability is not required.
Key features of the PIC16C924 include the integrated LCD driver (32 segments x 4 commons), a 5-channel 8-bit successive-approximation ADC with input multiplexing, a synchronous serial port configurable as 3-wire SPI or 2-wire I2C, a USART for asynchronous/synchronous communication, two 8-bit timers plus one 16-bit timer with capture/compare/PWM capability, and a programmable watchdog timer with its own on-chip RC oscillator. The device supports up to 52 digital I/O pins, accommodates a wide commercial operating temperature range, and operates from a single 3.0 V to 6.0 V supply.
Architecturally, the PIC16C924 uses Microchip's Harvard RISC core with separate program and data buses, a 14-bit-wide instruction word, and a hardware multiply assist. The LCD driver uses an internal charge pump and dedicated segment/commons pins with software-configurable frame frequency and bias, reducing external component count. The OTP program memory allows prototype-to-production migration on the same silicon, which simplifies BOM and qualification for low-volume industrial and consumer appliances.
Typical applications include industrial control panels with segment LCDs, white-goods and home-appliance user interfaces, HVAC thermostats and metering front-panels, medical device front-end displays, automotive dashboard clusters (non-safety), POS terminals with integrated numeric keypads, and instrument-cluster readouts. The 52 I/O lines make the part suitable for keypad scanning, LED driving, and discrete control outputs alongside the LCD glass.
Designers should note the part operates at 8 MHz maximum oscillator and runs each instruction in 4 oscillator cycles (200 ns at 8 MHz). Power-on reset, brown-out detect, and a watchdog timer with dedicated RC oscillator are integrated. Use decoupling capacitors of 0.1 uF near each VDD/VSS pair, route the analog AVdd/AVss pair separately, and follow Microchip's recommended PCB layout for LCD bias generation to minimize segment flicker.

Industrial Control Panel with Segment LCD
The PIC16C924-08/PT is purpose-built for industrial front-panel HMIs that need a 32-segment x 4-common LCD without an external segment driver. Its 52 digital I/O lines drive keypad matrix scanning (up to 8x8), discrete status LEDs, and relay outputs, while the integrated 5-channel 8-bit ADC reads potentiometers, NTC temperature sensors, or 4-20 mA loop shunts. The 8 MHz core executes the LCD refresh ISR, button debounce, and Modbus RTU framing on the USART with margin to spare, all in a single chip that fits inside the panel cutout. The OTP program memory protects proprietary set-point tables against firmware extraction by competitors.

White-Goods and Home Appliance User Interface
Washing machines, dishwashers, ovens, and microwave ovens all need a 7-segment or custom-icon LCD plus tactile buttons and a few analog sensors. The PIC16C924-08/PT's on-chip 32-segment LCD driver eliminates the need for an external HT1621 or similar segment driver, reducing BOM and PCB area. The 5-channel ADC handles temperature sensing (NTC), door-switch status, and rotary encoder position; the 16-bit CCP module drives a buzzer for end-of-cycle alerts. Operating from 5V and tolerant of motor-noise on the supply rail, the device suits appliances with brushed universal motors.

HVAC Thermostat and Metering Front Panel
Residential and light-commercial thermostats need a backlit segment LCD showing set-point, ambient temperature, fan speed, and system mode. The PIC16C924-08/PT drives the LCD glass directly, scans the up/down/set buttons, and reads the temperature sensor (NTC or MCP9700) through one of its 5 ADC channels. The USART links to the indoor unit's main board for set-point reporting, while the watchdog timer with its dedicated RC oscillator provides a safety net against firmware lockup. Industrial temp grade is available as PIC16C924-08I/PT for outdoor equipment.

POS Terminal Numeric Keypad and Display
Point-of-sale terminals need a numeric 16-key keypad, a small 32-segment LCD for transaction amount display, and a serial link to the main terminal. The PIC16C924-08/PT handles all three: 16 keypad pins scan via PORTB, the integrated LCD driver renders the amount, and the USART/SSP talks to the main controller. The OTP program memory protects payment-processing logic from firmware extraction - critical for retail security certifications. 176 bytes of SRAM buffer keystrokes between interrupts, and the 8 MHz core keeps response latency under 50 ms.

Medical Device Front-End Display
Non-critical medical front-ends such as blood-pressure monitors, glucose meters, and pulse-oximeter displays use a segment LCD plus a few buttons. The PIC16C924-08/PT's integrated 32-segment driver renders systolic/diastolic readings directly on the LCD glass, while the 5-channel ADC digitizes the pressure transducer or photodiode signal. The PIC16C9xx family's deterministic instruction timing simplifies FDA 510(k) firmware validation, and the OTP memory prevents post-market firmware tampering that could alter calibration. Operating from 3 to 6 V lets the device run directly from 2xAA cells via a boost converter.

Instrument Cluster Readout (Non-Safety)
For low-speed vehicle or industrial equipment instrument clusters that need an alphanumeric LCD readout plus push-buttons (non-safety functions such as trip-computer, hours-of-operation, fuel-economy displays), the PIC16C924-08/PT fits naturally. The 32-segment LCD driver accommodates 8-digit 7-segment plus icons for mode indication, while the 5-channel ADC reads the fuel-level sender and battery voltage. The automotive-grade variant PIC16C924-08I/PT extends temperature range to -40C to +85C for under-dash mounting. The USART connects to a gateway ECU for OBD-II data passthrough.

Educational 8-Bit Microcontroller Platform
Universities and training centers continue to teach 8-bit RISC fundamentals on PIC microcontrollers, and the PIC16C924-08/PT's integrated LCD driver, ADC, USART, and 52 I/O pins make it a one-chip lab platform. Students learn instruction pipelining, interrupt-driven LCD refresh, and keypad scanning on a single 64-pin TQFP that exposes every peripheral pin. The OTP variant encourages disciplined firmware development because every programming cycle consumes a part - mirroring real production engineering trade-offs where code-lock security matters more than reprogrammability.

ڈیزائن نوٹس
The PIC16C924-08/PT operates from a single 3.0 V to 6.0 V VDD with a separate AVdd/AVss pair for the ADC. Place a 0.1 uF decoupling capacitor within 5 mm of each VDD pin and a 10 uF bulk capacitor at the board input. AVdd should be tied to VDD through a small ferrite bead or 10 ohm resistor with its own 0.1 uF + 10 uF decoupling to keep ADC reference noise below 1 LSB. The internal LCD charge pump can source up to 5 mA - budget this when calculating total VDD current at low supply voltages where regulator dropout becomes significant.
Do not assume 100 % code-compatibility between PIC16C924 and PIC16F924 - register names, interrupt vectors, and Flash programming timing differ. New designs should target PIC16F924-I/PT directly to gain Flash reprogrammability, ICSP debugging, and nanoWatt power-saving modes. When migrating an existing C924 firmware to F924, recompile against the new header file and re-validate interrupt latency because the Flash wait-state timing differs from OTP. Brown-out detect voltage must be re-configured if the application requires a different BOD threshold than the C924 default.
Route the LCD segment and common pins on an inner layer with a ground plane on the opposite side to minimize coupling. Keep segment traces short (under 50 mm) and matched in length within a group to avoid ghosting. Place the VLCD bypass capacitor within 5 mm of the VLCD pin, and use the recommended 1 uF X7R ceramic. For 64-pin TQFP layout, allocate a continuous ground plane under the package and stitch vias on a 5 mm grid to suppress radiated EMI from the charge-pump switching edges, which can couple into analog ADC channels.
