PIC16C67-10E/L - 8-Bit 14KB OTP MCU 10MHz 44-PLCC | Microchip
MPN: PIC16C67-10E/L ✓ Hoạt độngPIC16C67-10E/L Tóm tắt
An 8-bit OTP microcontroller is a Harvard-architecture processor that executes single-cycle instructions from on-chip EPROM (erasable PROM) that is one-time programmable, meaning the code is committed after programming and the device cannot be electrically rewritten. The PIC16C6X family sits within Microchip's mid-range PICmicro hierarchy: PIC16C6X -> mid-range 8-bit -> PICmicro -> microcontroller -> embedded IC. These devices remain popular for legacy industrial, automotive, and white-goods designs where deterministic interrupt response, simple development flow, and long-term supply stability matter more than raw computational throughput.
Key features include 14KB OTP program memory, 368 bytes of RAM, a 12-bit ADC with up to 8 channels, a USART with on-chip baud-rate generator, three 16-bit timer/counters, a synchronous serial port (SSP) supporting SPI and I2C master/slave modes, a parallel slave port, 33 digital I/O pins, and a low-power sleep mode that draws roughly 1 uA typical at 3 V / 32 kHz. The wide 2.5 V to 6.0 V operating range (with 4.5 V to 5.5 V at full 10 MHz speed) lets the same firmware run across 3.3 V battery and 5 V industrial rails.
Architecturally, the PIC16C67 uses a 14-bit instruction word, an 8-level hardware stack, and separate instruction/data buses (Harvard), giving it predictable single-cycle execution except for two-cycle program branches. The CMOS EPROM cell array provides non-volatile code storage for the lifetime of the product.
Typical applications include industrial process control, motor control signal conditioning, HVAC fan/blower controllers, automotive body electronics, security and access-control panels, point-of-sale terminals, white-goods user-interface boards, and embedded sensor hubs. Its 33 I/O pins easily drive keypad matrices, character LCDs, and relay banks. The Extended temperature grade suits outdoor enclosures and under-hood automotive modules.
A key design tip: the device is OTP, so plan for windowed (UV-erasable) prototype parts during firmware iteration; once the firmware is finalized, commit to the plastic OTP version for production. Compared with modern PIC16F1xx flash parts, the PIC16C67 trades re-programmability for BOM cost and proven long-term availability.
This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes drawn from the Microchip PIC16C6X datasheet family - information that goes beyond the manufacturer datasheet by offering parametric proximity scores, board-level replacement guidance, and obsolete-part sourcing context.

Ứng dụng tiêu biểu
PIC16C67-10E/L phù hợp cho 6 Áp dụngs: Industrial Process Control Front-Ends, Automotive Body Electronics and HVAC, Security and Access Control Panels, White-Goods User-Interface Boards, Point-of-Sale and Kiosk Terminals, Embedded Sensor Hubs and Data Loggers.
Industrial Process Control Front-Ends
The PIC16C67-10E/L suits industrial process control front-ends because its 33 digital I/O pins drive multi-channel sensor multiplexing and its on-chip ADC (up to 8 channels) digitizes thermocouple, RTD, or 4-20 mA loop signals without an external ADC IC. The Extended temperature grade (E suffix) and 2.5 V to 6.0 V supply range let it survive factory-floor voltage swings, while the USART streams data back to a PLC. Designers frequently pair it with an RS-485 transceiver for long-line connectivity to a SCADA host.

Automotive Body Electronics and HVAC
The PIC16C67-10E/L with Extended temperature grade is well matched to automotive body and HVAC control modules that don't require AEC-Q100 qualification. Its 33 I/O drive brushless DC fan commutation, stepper motor air-recirc doors, and HVAC mode-selector switches; the three 16-bit timers generate the PWM channels. The 10 MHz instruction throughput is sufficient for control-loop rates up to ~50 kHz and fault-debounce filtering. Production OEMs typically migrate to PIC16F877A-I/P for flash re-programmability, but the OTP part remains in long-life service parts.
Được đề xuất
Security and Access Control Panels
In security and access-control panels the PIC16C67-10E/L serves as the keypad/credential scanner plus relay-control brain. The 33 I/O directly scan a 4x4 keypad matrix and a 16-character LCD while still leaving headroom for relay banks driving door strikes. Its low-power sleep mode (~1 uA typical at 3 V / 32 kHz, per the PIC16C6X datasheet) extends battery life in wireless panic-button peripherals. OTP programming secures the firmware against reverse engineering of physical access algorithms.

White-Goods User-Interface Boards
Washing machines, dishwashers, and microwave ovens use PIC16C67-10E/L on the user-interface PCB to drive 7-segment displays, capacitive or resistive keypads, and buzzer feedback. The part's deterministic Harvard-architecture instruction execution and 8-level hardware stack simplify IEC 60730 safety-class-B firmware certification. The wide 2.5 V to 6.0 V operating range accommodates direct 5 V power rails from the appliance's SMPS without LDO regulation, reducing BOM cost in this price-sensitive segment.
Được đề xuất
Point-of-Sale and Kiosk Terminals
The PIC16C67-10E/L anchors point-of-sale terminals and unattended kiosks where its USART with on-chip baud-rate generator talks to a thermal printer and credit-card reader, while the SSP peripheral drives an SPI-connected NFC front-end. The 14 KB OTP holds both the user-interface state machine and the secure payment-flow stub. Designers pair it with external flash or EEPROM for transaction logging. The 10 MHz throughput handles barcode scanning, contactless card reads, and receipt printing with margin to spare.
Được đề xuất
Embedded Sensor Hubs and Data Loggers
For low-cost embedded sensor hubs and data loggers, the PIC16C67-10E/L combines its 8-channel ADC with a 33-I/O bus that drives a microSD card interface via SPI, sampling sensors at 100 Hz or less and logging to FAT-formatted media. The wide 2.5 V to 6.0 V supply range lets the device run directly from 4 AA cells (4.8 V typical, dropping to ~3.6 V at end-of-life). Sleep current of ~1 uA enables multi-month battery life in remote environmental sensor deployments.

Ghi chú thiết kế
The PIC16C67 is OTP (One-Time Programmable) - the firmware is committed on the first programming pass and cannot be electrically erased. Plan prototype cycles with the JW (windowed) or QTP (quasi-volume) variants, and burn the plastic OTP version only after the firmware is fully validated. Re-spinning an OTP part costs both the unit price and the production-programming slot. Source: Microchip PIC16C6X datasheet family programming specifications.
Place a 100 nF decoupling capacitor as close as possible to each of the four Vdd pins (10, 20, 38, 43) on the 44-pin PLCC and a single 10 uF bulk cap on the board's main supply trace. Long Vdd traces between physical pin 10 and pin 38 create voltage transients when PORTD (pins 29-36) switches eight outputs simultaneously. Source: Microchip PIC16C6X datasheet family hardware-design considerations.
Estimated: at 10 MHz and 5 V, active current is approximately 15 mA typical (per the PIC16C6X datasheet family). Sleep current with the WatchdogTimer disabled is roughly 1 uA typical at 3 V / 32 kHz. Plan battery life around these two regimes - for a sensor hub that wakes every 10 seconds, the average current is dominated by the wake-and-measure duty cycle, not by sleep leakage.
Pin 1 of the 44-pin PLCC is identified by a chamfered corner on the package top and a small dot on the bottom; orient the PCB silkscreen accordingly. The four Vdd/Vss pin pairs should each have their own short trace to the decoupling cap rather than daisy-chained power routing. Source: Microchip PIC16C6X datasheet family PLCC package drawing.
