PIC16C77-10/L - 8-Bit 10MHz OTP MCU, 14KB, 44-PLCC | Microchip
MPN: PIC16C77-10/L ✗ اختتامِ زندگیPIC16C77-10/L جائزہ
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (ROM/Flash/EPROM), data memory (RAM), and peripherals such as timers, I/O ports, ADCs, and communication interfaces. The PIC16C77 belongs to the mid-range PIC16C family, positioned within the PIC architecture hierarchy of PIC10/12/14/16/18/24/dsPIC families, and is built on OTP (One-Time Programmable) EPROM technology, meaning the program memory can be written only once but offers mature, well-characterized CMOS behavior.
Key features include 33 digital I/O lines, an 8-channel 8-bit A/D converter, three timers (Timer0, Timer1, Timer2), a USART module for serial communication, and an instruction execution time of 200 ns at 10 MHz. The device operates from 4.0 V to 6.0 V across an industrial temperature range of -40 °C to +85 °C, and is upward code-compatible with PIC16C5X and PIC12CXXX devices, easing migration for legacy designs.
Architecturally, the PIC16C77 uses a Harvard-style RISC core with 35 single-word instructions, a hardware stack of 8 levels, and direct/indirect addressing modes. Its CMOS-EPROM process gives low standby current (~1 µA typical) and robust noise immunity, while on-chip peripherals such as the Capture/Compare/PWM module and the parallel slave port make it suitable for embedded control tasks without external glue logic.
Typical applications include industrial automation controllers, motor control front-ends, instrumentation with analog sensing, automotive body electronics modules, and legacy embedded systems requiring a 5 V supply rail. The 33 I/O pins allow direct connection to keypads, LED or LCD displays, and analog sensors through the integrated ADC.
When designing with the PIC16C77-10/L, note that OTP memory cannot be erased, so firmware must be fully verified before programming; a windowed UV-erasable variant (PIC16C77JW) is recommended for prototype development. The 44-PLCC footprint simplifies through-hole and socketed assembly, supporting field-replaceable modules in industrial equipment.

PIC16C77-10/L کے لیے موزوں ہے 6 ایپلیکیشنs: Industrial Process Control, Motor Control Front-End, Instrumentation with Analog Sensing, Automotive Body Electronics, Embedded HMI Keypad/Display Controllers, Legacy Embedded System Maintenance.
Industrial Process Control
The PIC16C77-10/L fits industrial process controllers because it delivers 33 digital I/O lines, 8 channels of 8-bit ADC, and a USART for host communication on a single 5 V rail. Its 14 KB OTP program memory accommodates mid-sized ladder-logic or state-machine code, while the Harvard RISC core provides deterministic 200 ns instruction timing for time-critical loops. The industrial -40 to +85 °C temperature range suits factory-floor deployments, and the 44-PLCC package supports socketed modules for fast field replacement.

Motor Control Front-End
In motor-control subsystems the PIC16C77-10/L serves as the command and feedback front-end, generating PWM via its Capture/Compare/PWM module and reading back encoder or current-sense signals through the ADC. The 10 MHz instruction cycle provides 200 ns resolution, enough for sub-millisecond torque loops on fractional-horsepower DC or stepper drives. With 33 I/O, the MCU can multiplex bridge driver controls, fault inputs, and HMI buttons without external glue logic.
تجویز کردہ
Instrumentation with Analog Sensing
The integrated 8-channel 8-bit ADC makes the PIC16C77-10/L suitable for multi-sensor instruments such as temperature loggers, weigh scales, or gas-detection boards. Each ADC conversion completes in roughly 20 µs, allowing up to 50,000 samples per second aggregate, which exceeds the update requirements of most low-bandwidth instrumentation. The 368 bytes of RAM buffer instantaneous readings while the USART streams them to a host PC or display module.

Automotive Body Electronics
Within 12 V-derived automotive body modules (seat controllers, mirror adjusters, climate panels) the PIC16C77-10/L functions as a 5 V logic island providing switch scanning, lighting PWM, and LIN-style serial communication through its USART. The MCU's CMOS-EPROM design is rugged against automotive electrical transients when paired with external TVS protection. Industrial temperature rating of -40 to +85 °C covers cabin and under-hood zones, and 33 I/O lines accommodate multi-channel body loads.
تجویز کردہ
Embedded HMI Keypad/Display Controllers
The PIC16C77-10/L drives small HMIs that combine 4x4 keypads, 7-segment or character LCDs, and indicator LEDs, because its 33 I/O pins can scan a matrix keypad and refresh an LCD bus directly. At 10 MHz the firmware can debounce keys and refresh displays in real time without missing presses. The USART enables updates from a master controller, making this MCU a flexible peripheral in larger distributed-embedded systems.
تجویز کردہ
Legacy Embedded System Maintenance
The PIC16C77-10/L is a direct fit for maintenance of long-lifecycle industrial or military systems originally designed around the PIC16C7X family, where OTP memory prevents unauthorized field firmware updates and the 44-PLCC package enables socketed board-level replacement. The MCU's mature CMOS-EPROM process is widely understood and supported by legacy compilers and emulators. Designers can perform drop-in board swaps using PIC16C77-04/L, -20/L, or industrial -I variants with identical pinouts.

ڈیزائن نوٹس
The PIC16C77-10/L uses OTP EPROM which cannot be electrically erased. Verify all firmware logic on a windowed UV-erasable variant (PIC16C77JW) or use a development toolchain with full simulation before programming production units. In-circuit programming is not supported on OTP parts, so failed programming yields scrap parts. Allow a programming-margin margin of at least 10 % above the Vpp spec during in-circuit programming.
Place a 100 nF decoupling capacitor as close as possible to the Vdd pins (pins 14 and 41 on the 44-PLCC) with a short trace to Vss. Add a 10 µF bulk capacitor at the board entry point to suppress noise injected by relay coils or motor loads. The PIC16C77-10/L is rated for 4.0 V to 6.0 V; operation outside this range can cause memory corruption or ADC reference drift. Estimated: typical operating current is 5 mA active and 1 µA standby.
The 44-pin PLCC package provides J-leads that wrap under the package body; ensure the land pattern follows JEDEC MS-018 guidelines with at least 0.5 mm pad overhang. For socketed designs, use a Mill-Max or 3M Textool PLCC socket to allow field replacement. Keep the crystal oscillator traces (OSC1/OSC2) under 10 mm and surround them with a ground guard ring to avoid noise coupling into the internal oscillator.
