PIC16C54-10E/P - 8-bit OTP MCU 10MHz 768B | Microchip Technology
MPN: PIC16C54-10E/P ✗ Cuối đờiPIC16C54-10E/P Tóm tắt
What is an 8-bit OTP microcontroller? An 8-bit OTP microcontroller is a small, self-contained computer-on-a-chip that uses an 8-bit data path and stores its program in One-Time Programmable EPROM memory. OTP variants sit in the product hierarchy between masked-ROM devices (cheapest at high volume, but require NRE charges) and Flash devices (re-programmable in-circuit); they are widely used where low-to-medium volume production requires field programmability without the cost of a windowed UV-eraseable part.
Key features of the PIC16C54-10E/P include 33 single-word instructions (all single-cycle at 200 ns except program branches which take two cycles), a RISC architecture, a Power-On Reset (POR) circuit, a Watchdog Timer (WDT) for reliable operation, and an 8-bit timer/counter. The device operates from 3.0 V to 5.5 V and supports in-circuit serial programming (ICSP) via dedicated pins.
The PIC16C5X family uses a Harvard architecture with separate program and data buses, allowing instruction fetch and operand access to occur simultaneously. This RISC-style design gives deterministic 200 ns instruction execution at 10 MHz and produces highly compact code (2:1 compression versus typical 8-bit CISC controllers in the same class).
Typical applications include appliance controllers, automotive subsystems (body electronics, sensor interfaces), industrial controls, low-end remote keyless entry, security system panels, and any cost-sensitive embedded application that benefits from a proven, mature 8-bit core. The Extended temperature grade makes the PIC16C54-10E/P suitable for harsh-environment installations.
A key design consideration: OTP memory cannot be re-programmed, so code must be fully validated before committing. For prototyping or in-field firmware updates, consider the Flash-based PIC16F54 equivalent (same pinout, same peripherals) before committing the design to OTP. Brown-out detection is not present on this part; use external POR supervision if VDD rise time is slow.

Ứng dụng tiêu biểu
PIC16C54-10E/P phù hợp cho 6 Áp dụngs: Appliance Control Boards, Automotive Body Electronics, Industrial Sensor Interfaces, Remote Keyless Entry (RKE) and Security Panels, Low-End Consumer Remote Controls, Educational and Hobbyist Embedded Projects.
Appliance Control Boards
The PIC16C54-10E/P's 10 MHz core, 12 I/O pins, and Watchdog Timer make it well-suited to washing-machine, dishwasher, microwave and HVAC controller boards. The Extended -40 °C to +125 °C temperature grade handles under-cabinet or motor-compartment thermal stress. The 33 single-word RISC instructions fit small C or assembly state machines for relay, valve, and triac-drive sequencing. Estimated: at VDD=5 V and 4 MHz active, current draw is approximately 2 mA, suitable for always-on appliance electronics. Compared with masked-ROM equivalents, OTP allows late-stage firmware changes during model-year transitions without re-masking charges.

Automotive Body Electronics
Body-electronics modules such as seat controllers, mirror adjusters, lighting dimmers and simple sensor interfaces benefit from the PIC16C54-10E/P's Extended temperature grade and 12-bit instruction compression. The 200 ns instruction cycle is fast enough for 10 ms-class CAN-style bit timing or LIN slave bit-banging at 19.2 kbps. Brown-out handling relies on the internal Power-On Reset circuit; pair with an external MCP130 supervisor for crank-voltage transients. OTP memory prevents accidental in-field reprogramming by unauthorized tools - an advantage for safety-relevant nodes. Estimated quiescent current below 1 µA in sleep mode keeps battery drain acceptable for parked vehicles.

Industrial Sensor Interfaces
Low-speed industrial sensor conditioning nodes - thermocouple cold-junction compensators, 4-20 mA loop read-backs, photo-eye interfaces - use the PIC16C54-10E/P as a low-cost ADC-replacement signal processor. The 8-bit timer/counter generates PWM excitation for resistive-bridge sensors at kHz-class frequencies. 12 I/O pins accommodate 4-6 sensor channels plus indicator LEDs and a UART link. The RISC architecture keeps interrupt latency deterministic at 200 ns. Pair with an MCP602 op-amp for signal conditioning and a TLP181 optocoupler for loop isolation. Estimated ADC throughput of 8 ksamples/s using successive-approximation techniques is achievable in firmware.

Remote Keyless Entry (RKE) and Security Panels
Low-cost RKE fobs, garage-door keypads, and PIR-triggered alarm panels fit easily in 768 bytes of PIC16C54-10E/P OTP. The 10 MHz core performs rolling-code encryption or simple fixed-code transmit sequencing within microsecond budgets. The Watchdog Timer recovers from RF-induced firmware lockups. Sleep current well under 1 µA on coin-cell batteries gives multi-year standby. The Extended temperature rating tolerates glove-compartment or outdoor-cabinet extremes. Use a 433 MHz SAW-resonator transmitter (e.g., MICRF102) or an ASK/OOK module for the RF link. Estimated battery life exceeds 5 years at <0.1 % duty cycle.

Low-End Consumer Remote Controls
TV, set-top-box, fan and lighting remote controls are a natural fit for the PIC16C54-10E/P. The 12 I/O pins scan a 4×4 or 5×3 keypad matrix with zero external components, while the 8-bit timer/counter generates IR carrier at 38 kHz or 56 kHz. The Extended temperature grade prevents summer-window sill failures. OTP eliminates accidental user erasure in the field. Typical 2 mA active current at 4 MHz yields >1 year battery life from a pair of AA cells. Pair with a TSOP38238 IR receiver for the receiver side. Estimated code density allows 50-80 button commands in 768 B.

Educational and Hobbyist Embedded Projects
The PIC16C54-10E/P remains a teaching staple because of its 33-instruction RISC core that fits on a single page of a textbook and its deterministic timing that beginners can reason about. Through-hole PDIP is breadboard-friendly for schools and makerspaces. Although the Extended temperature grade and OTP memory are over-spec for classroom use, the price differential is small. For learner projects that need reprogramming, drop in the PIC16F54-I/P - same 18-pin PDIP footprint. Pair with the PICkit 3 / PICkit 4 programmer and MPLAB X IDE for the development flow. Estimated learning curve: blink an LED in 6 instructions.

Bảo phân biệt quan trọng
- Extended temperature grade (-40 °C to +125 °C) in a through-hole 18-PDIP package (vsPIC16C54-10/P)

Ghi chú thiết kế
The PIC16C54-10E/P operates from 3.0 V to 5.5 V. At 10 MHz active current is approximately 2.5 mA at 5 V (estimated from PIC16C5X family typicals), dropping to <1 µA in sleep. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of pin 14, plus a bulk 10 µF tantalum at the regulator output. The internal Power-On Reset (POR) handles VDD rise times up to ~50 ms; for slower ramps, supervise VDD externally with an MCP130 or equivalent to avoid code execution from invalid memory states.
Keep the 18-PDIP footprint on a 0.100-inch (2.54 mm) row pitch with 0.300-inch row-to-row span to match standard IC sockets and breadboards. Place the decoupling capacitor within 5 mm of VDD (pin 14) and the crystal/ceramic resonator within 5 mm of OSC1/OSC2 (pins 16/15). Route the MCLR/VPP line (pin 4) directly to the ICSP header with no series resistance above 10 kΩ to ensure reliable in-circuit programming. Keep high-current switching traces (relay coils, triacs) away from the oscillator pins to avoid EMI-induced clock jitter.
Critical pitfalls: (1) Brown-out detection is NOT present - use external voltage supervision if VDD can droop below 3 V under load. (2) OTP memory cannot be re-programmed - validate firmware with a Flash-based PIC16F54-I/P before committing to OTP production. (3) The '/P' suffix denotes through-hole PDIP which is NOT RoHS compliant; use '/SO' or '/SS' for lead-free products. (4) Branch instructions take 2 cycles (400 ns) - account for this when computing tight timing loops such as UART bit-banging or IR carrier generation.
Thông tin tuân thủ
18-pin PDIP through-hole package contains lead and is not RoHS compliant. For RoHS-compliant designs, choose the surface-mount PIC16C54-10E/SO or PIC16C54-10E/SS variant. AEC-Q100 qualification is not stated on the Microchip product page - contact Microchip for automotive PPAP documentation if required.
