The Microchip Technology PIC16C771/JW is an 8-bit CMOS OTP-based mid-range microcontroller featuring a 20 MHz core (200 ns instruction cycle), 7 KB of UV-erasable EPROM program memory organized as 4K x 14 words, and 256 bytes of data RAM, housed in a 20-pin ceramic CDIP (JW) windowed package. Its headline differentiating feature is an integrated 12-bit A/D converter with 6 input channels, which removes the need for external ADC ICs in precision analog measurement applications. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and programmable peripheral interfaces. PIC16C77x-series MCUs belong to Microchip's PIC16 mid-range family, which sits hierarchically between the baseline PIC10/12/16 families and the enhanced PIC18 family, and is fully upward code-compatible with the PIC16C5X and PIC12CXXX legacy devices. Mid-range PIC MCUs execute 35 single-word instructions, support interrupts and a hardware multiplier, and provide deterministic real-time control for embedded designs. Key features of the PIC16C771/JW include 6 channels of 12-bit ADC, an instruction cycle of 200 ns at 20 MHz, 256 bytes of SRAM, 256 bytes of EEPROM data memory, and a synchronous/asynchronous serial port (USART/SCI).

The JW ceramic windowed package is required for prototype development and engineering validation because it allows UV erasure of the EPROM. Architecturally, the PIC16C771/JW uses a Harvard-class pipelined RISC core with separate program and data buses, allowing an instruction fetch to occur concurrently with operand read. The 12-bit ADC is a successive-approximation converter with internal sample-and-hold, supporting both single-ended and differential inputs, and selectable reference voltages from VDD or an external pin, which lets designers optimize the dynamic range for low-level sensor signals. Typical applications include industrial process control, precision analog signal acquisition, instrumentation front-ends, sensor-conditioning firmware, and low-cost data loggers. The combination of 12-bit ADC, USART, and PWM makes the part a single-chip solution for closed-loop motor control, smart sensor modules, and battery monitoring circuits where deterministic 8-bit execution is sufficient. When designing with the PIC16C771/JW, note that the JW (ceramic windowed CDIP) package is intended for development only - in production, migrate to a plastic OTP (P) or windowless variant. Operating voltage is 4.0 V to 6.0 V across 0 °C to 70 °C (commercial); the EPROM must be erased with UV light through the window before reprogramming, and code-protect fuses must be set correctly to prevent unintended memory read-out. This page synthesizes distributor pricing, UV-EPROM-aware design notes, and pin-compatible drop-in alternatives not consolidated on the manufacturer datasheet, providing a single reference for both new designs and legacy EPROM retrofits.

PIC16C771T/SO - 8-Bit OTP MCU, 7KB, 12-bit ADC, SOIC-20

The Microchip Technology PIC16C771T/SO is an 8-bit CMOS OTP-based microcontroller in the PIC16C family, delivering 200 ns instruction execution and packaged in a 20-pin SOIC (0.295", 7.50 mm width) form factor. Per Microchip's official product page, the device ships with 7 KB of OTP program memory (4K x 14 words), operates from a 5 V supply, and is pin-compatible upward with the PIC16C5X and PIC12CXXX device families, easing migration for legacy designs. The "/SO" suffix denotes the SOIC-20 surface-mount package and the "T" suffix indicates tape-and-reel packaging. An 8-bit OTP microcontroller is a microprocessor that combines a CPU core, non-volatile One-Time-Programmable program memory, RAM, and peripherals on a single die. OTP devices are programmed once with a device programmer and retain their code indefinitely, which makes them economical for high-volume embedded products where firmware is stable and field re-programmability is not required. The PIC16C architecture sits within a broader hierarchy: microcontroller -> embedded controller -> integrated circuit -> semiconductor, and Microchip's PIC16C line remains one of the most widely deployed 8-bit cores in industrial control. Key features of the PIC16C771 include 35 single-word instructions, an operating speed of 20 MHz, and 6 channels of 12-bit Analog-to-Digital (A/D) conversion that deliver higher measurement resolution than the typical 8-bit ADCs found on legacy PIC16C devices. The device retains the classic PIC16C peripheral set including timers, USART, capture/compare/PWM, and a small RAM/SRAM footprint suitable for tight real-time loops. Architecturally, the PIC16C771 uses a Harvard-style RISC core with separate program and data buses, an accumulator-based ALU, and a peripheral set tuned for deterministic bit-manipulation and low-latency interrupt response. The 12-bit ADC allows direct interfacing with precision sensors, eliminating an external ADC chip and shrinking the bill of materials. The wide SOIC-20 package also exposes enough I/O for keypad, display, and serial communication interfaces in parallel. Typical applications include industrial automation controllers, sensor signal conditioning with on-chip 12-bit ADC, motor-control PWM peripherals, and legacy product retrofits where PIC16C5X source code must be ported forward. The device is also commonly used as a single-chip replacement for older PIC16C7X designs that do not require in-system Flash programmability. When designing with this OTP device, be aware that code is committed permanently after programming - any firmware bug discovered after production requires a mechanical part swap rather than a field re-flash. Plan for either factory programming only, or migrate to a pin-compatible PIC16F series Flash variant if field updates are anticipated. The PIC16C771 is recommended only when OTP cost advantages justify the loss of re-programmability. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet, giving engineers a single source to evaluate the PIC16C771T/SO against modern equivalents.

PIC16C parts are OTP (One-Time Programmable) CMOS devices, historically positioned as a stepping stone between early EPROM-based PIC16C5X and later flash-based PIC16F families, and they are upwards code-compatible with PIC12CXXX and PIC16C5X devices. Key features of the PIC16C771 include a 12-bit ADC with up to 6 input channels (the highest resolution in this class at introduction), a 20 MHz maximum clock for 5 MIPS throughput, an internal oscillator option, a watchdog timer with its own on-chip RC oscillator for fail-safe operation, and an operating voltage range of 2.5 V to 5.5 V. Brown-out Reset and Power-on Reset circuits are integrated, and in-circuit serial programming is supported for development workflows. Typical applications include industrial sensor signal conditioning with high-resolution analog front ends, battery charging controllers, closed-loop fan/pump control, instrumentation front panels, and low-cost consumer products that need 12-bit ADC precision without the cost of an external converter. The combination of OTP memory, small SSOP-20 footprint, and 12-bit ADC makes it attractive where code is finalized in production. When designing with this part, note that PIC16C771 is OTP, not Flash, so firmware must be finalized before programming. Allocate sufficient ADC acquisition time and use the internal RC oscillator only when timing tolerance is non-critical. Decouple VDD/VSS with 100 nF + 10 µF capacitors placed close to the pins. This page synthesizes distributor pricing, parametric drop-in alternatives from Microchip's own PIC16 family, and practical design notes that go beyond the manufacturer datasheet to help engineers evaluate the part quickly.

The device executes instructions at 200 ns per instruction cycle (5 MIPS at 20 MHz clock) and is housed in a 28-pin SPDIP through-hole package. The -E suffix denotes the extended operating temperature range of -40C to +125C, suitable for industrial and harsh-environment deployments. An 8-bit microcontroller (MCU) is a programmable integrated circuit that combines a CPU, memory, and peripherals on a single die. The PIC16C architecture is a Harvard RISC design, separating program and data buses to allow simultaneous instruction fetch and operand access, which improves throughput over von-Neumann designs. Within the broader semiconductor taxonomy, the PIC16C family falls under microcontrollers, a sub-category of microprocessors and digital ICs. The 16C series uses OTP EPROM technology, meaning each chip is one-time field-programmable and retains code without a window (unlike the JW ceramic-windowed variants used for prototyping). Key features include 22 digital I/O pins, three timer/counters, a synchronous/asynchronous USART with 9-bit address detection, a 12-bit ADC with 6 channels, and a Capture/Compare/PWM (CCP) module. The integrated 12-bit ADC provides 4096 discrete steps, enabling discrimination of small analog signal changes without external signal-conditioning circuitry. Brown-out Reset (BOR) circuitry and a Watchdog Timer (WDT) with on-chip RC oscillator enhance reliability in unattended or electrically noisy environments. The device operates from 4.0V to 5.5V supply and supports In-Circuit Serial Programming (ICSP) via two pins, allowing firmware updates after PCB assembly. Typical applications include industrial process-control sensor interfaces, HVAC damper/valve actuators, multi-channel data acquisition front-ends, instrumentation panels with keypad/display, and embedded motor-control interfaces. The extended temperature range makes it suitable for outdoor or under-hood industrial environments. When designing with this device, ensure VDD decoupling includes both bulk (e.g. 10 uF) and high-frequency (100 nF) capacitors placed within 5 mm of the supply pins. For ADC accuracy, add a 10 uF + 100 nF analog supply (AVDD) bypass network. The OTP nature means firmware cannot be erased; use JW windowed parts for development cycles and only move to OTP for production runs. This page consolidates distributor pricing, parametric cross-references, and engineering design notes that go beyond the manufacturer datasheet alone.

The 12-bit ADC integrates sample-and-hold and supports both single-ended and differential conversions with selectable acquisition time, allowing direct interfacing to sensors without external analog conditioning. The on-chip voltage reference and oscillator options reduce external component count. Typical applications include industrial process control, sensor signal conditioning, instrumentation data acquisition, motor control feedback loops, and embedded measurement systems. The 12-bit ADC is particularly attractive for precision temperature, pressure, and flow measurement where 10-bit conversion is insufficient but full 16-bit signal-chain cost is unjustified. When designing with this part, designers must remember that OTP memory cannot be re-programmed in-circuit; for prototyping, the PIC16C773-I/SS (Industrial temperature grade) or windowed CERDIP PIC16C773/JW variants are recommended. Adequate decoupling (100 nF ceramic close to VDD) and proper MCLR reset network are critical for ADC accuracy.

The 4-5.5V operating range, automotive -40C to +125C temperature grade (designated by the E suffix), and 12-bit ADC make it appropriate for harsh-environment analog measurement tasks. The OTP memory architecture suits designs with locked firmware images where the lower per-unit cost of OTP outweighs the field-reprogrammability of Flash-based PIC16F variants. A key design consideration for the PIC16C773T-E/SS is that OTP memory cannot be erased or rewritten, so the firmware must be fully validated before production programming. Engineers migrating from Flash-based PIC16F equivalents must use the same development toolchain (MPLAB X IDE, MPASM assembler, or C18 compiler) but plan for one-time-programming flow.

What is a PIC16C 8-bit OTP microcontroller? It is a member of Microchip's mid-range PICmicro family built on a CMOS process and packaged in OTP (One-Time-Programmable) memory. It belongs to the broader taxonomy: 8-bit microcontroller -> embedded MCU -> microcontroller IC -> integrated circuit -> semiconductor. PIC mid-range MCUs are widely adopted in industrial control, instrumentation, and automotive subsystems because of their deterministic instruction timing, low power consumption, and a mature toolchain (MPLAB IDE + MPASM / XC8). Key differentiating features include 10 channels of 12-bit ADC (vs 8-bit ADC on many older PIC16C6x devices), three timer/counters (TMR0, TMR1, TMR2), a USART with hardware addressing, a synchronous serial port (SSP) for SPI / I2C, a Capture/Compare/PWM (CCP) module, and a programmable Brown-out Reset (BOR). The 'E' temperature grade extends operation from -40C to +125C, making the PIC16C774-E/P suitable for industrial and automotive-grade thermal environments. Architecturally, the device uses a Harvard bus with separate program (14-bit wide) and data (8-bit wide) paths, allowing instruction fetch and operand access in a single cycle. The 12-bit ADC is successive-approximation (SAR) type with a sample-and-hold front end and programmable acquisition time, and the analog reference can be tied to VDD, an external pin, or an internal bandgap on derivatives. Typical applications include industrial process control loops, multi-channel data acquisition front-ends, instrumentation front-panels, sensor signal conditioning, motor/valve control with closed-loop feedback, and automotive body/cluster subsystems where the extended temperature range is mandatory. The wide I/O count also supports keypad scanning and LCD drive. When designing with the PIC16C774-E/P, allocate at least one decoupling capacitor pair (100 nF + 10 uF) per VDD/VDDcore pin and keep the analog AVdd/AVss traces short and quiet. Because the part is OTP, code must be fully validated before programming; for engineering builds use the windowed PIC16C774/JW, and for production reprogrammability migrate to the flash-based PIC16F877A.

A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (program + RAM), and programmable I/O peripherals, used to sense, control, and communicate in embedded systems. PIC microcontrollers sit in the 8-bit MCU category within the broader microcontroller hierarchy (4-bit -> 8-bit -> 16-bit -> 32-bit MCUs -> embedded processors), are widely deployed for deterministic real-time control, and offer low power, low cost, and easy in-circuit programmability. The PIC16C774-E/PQ specifically combines general-purpose digital I/O with high-precision analog conversion, making it a hybrid digital-plus-analog MCU. Key features include 10 channels of 12-bit A/D conversion (giving designers the ability to discriminate smaller signal changes and reduce external analog signal conditioning), on-chip peripherals for brown-out detect/reset (BOR), power-on reset (POR), pulse-width modulation (PWM), and a watchdog timer (WDT), and serial connectivity via I2C, SPI, and UART/USART. The 12-bit ADC resolution offers 16x the resolution of common 10-bit converters, allowing direct interface with precision sensors without external ADCs. The PIC16C774 architecture uses a Harvard-style RISC core with separate program/data buses, 14-bit-wide instruction words, and an external oscillator interface. Compared with PIC16C7x predecessors that offer 8-bit ADCs, the 12-bit ADC widens dynamic range by approximately 16x and reduces quantization noise, enabling measurements previously requiring dedicated ADC ICs. The OTP program memory is one-time programmable in-circuit, allowing rapid prototyping without package-specific windowed erase cycles. Typical applications include industrial automation control, precision sensor signal acquisition, motor and valve control, consumer electronics with analog front ends, automotive body and chassis subsystems, and instrumentation requiring mixed-signal acquisition. The 33 I/O pins and 10 ADC channels suit designs that previously required a microcontroller plus an external ADC. When designing with this device, note that OTP memory cannot be erased in-circuit. For development, choose the JW windowed ceramic variant, and reserve engineering samples for in-system validation. Decoupling the VDD/VSS pair with 0.1 uF ceramic capacitors close to the pins and following Microchip's recommended oscillator layout minimizes EMI and improves ADC accuracy.

They excel in deterministic, bit-level control tasks and remain widely deployed where cost, simplicity, and real-time responsiveness outweigh the throughput demands satisfied by 32-bit cores. The PIC16C774 series belongs to Microchip's mid-range PIC16 family, which uses a 14-bit instruction word and Harvard architecture. Key features of the PIC16C774-E/PT include the 10-channel 12-bit ADC with up to 12 input channels (some shared with digital I/O), two 8-bit timers plus one 16-bit timer, a Universal Synchronous Asynchronous Receiver Transmitter (USART), a Synchronous Serial Port (SSP) supporting SPI and I²C, and a Capture/Compare/PWM (CCP) module. The device supports up to 20 MHz oscillator input and a 5 MIPS instruction throughput. Brown-out Reset (BOR), Power-on Reset (POR), and a Watchdog Timer with its own on-chip RC oscillator provide robust field reliability. Architecturally, the PIC16C774 pairs a Harvard bus with a 14-bit-wide program memory path and an 8-bit data path, which keeps the instruction fetch and execution overlapping for predictable 200 ns cycle times at 20 MHz. The OTP memory allows one-time factory or in-circuit programming of code and constants, making the part well-suited to low-to-medium volume production runs where mask-ROM economics are unfavorable. The 12-bit ADC uses a successive-approximation register with sample-and-hold, and dedicated analog inputs can be multiplexed across the 33 I/O pins. Typical applications include industrial process control loops, sensor signal conditioning, motor control front-ends, instrumentation data acquisition, automotive body electronics, and embedded control subsystems in medical and consumer appliances. The wide temperature range and 12-bit ADC precision particularly suit battery monitoring, multi-channel temperature scanning, and closed-loop analog control. In automotive body controllers, the same ADC bandwidth plus the USART links cleanly to LIN-based communication transceivers. When designing with the PIC16C774-E/PT, observe the absolute maximum VDD of 7.5V and decouple VDD with a 0.1 µF ceramic capacitor placed within 5 mm of the supply pin. Configure unused I/O as outputs and tie them to ground to minimize ADC noise injection. The MCLR pin should be tied through a 10 kΩ pull-up to VDD, with a 100 nF cap to ground for ESD hardening.

PIC16C774-I/L

PIC16C774-I/L - 8-bit OTP MCU 7KB EPROM 12-bit ADC | Microchip

The Microchip Technology PIC16C774-I/L is an 8-bit CMOS OTP-based microcontroller built on the PIC16C architecture, featuring 7 KB (4K x 14) of one-time-programmable program memory, 256 bytes of RAM, and 33 digital I/O lines, all integrated in a 44-pin PLCC package. It executes instructions in a 200 ns cycle (20 MHz clock) from a 35-instruction RISC set, providing 5 MIPS of throughput while maintaining a wide 4 V to 5.5 V supply range. What is an 8-bit OTP microcontroller? An 8-bit microcontroller (MCU) is a small computer-on-a-chip with an 8-bit data path, ALU, program memory, RAM, and integrated peripherals such as timers and ADCs. OTP (One-Time Programmable) program memory uses EPROM cells that can be written only once via a programmer and cannot be erased, making OTP parts a low-cost option for production volumes. PIC16C-series devices are mid-range Microchip parts in the PIC microcontroller hierarchy: PIC10/12/16/18 -> PIC16C (mid-range, 14-bit instruction) -> PIC16C77x family -> PIC16C774 specifically. Key features include 10 channels of 12-bit resolution Analog-to-Digital conversion (a notable upgrade over the 8-bit ADC of earlier PIC16C7x parts), a USART with addressable SPI/I2C support, two 8-bit timers plus one 16-bit timer with capture/compare/PWM, a Watchdog Timer, and dual analog comparators. The 12-bit ADC enables discrimination of smaller analog signal changes and eliminates the need for external precision analog front-end circuitry, simplifying sensor and instrumentation designs. The PIC16C774-I/L uses an industry-standard PIC16C RISC pipeline with a 14-bit program word and Harvard architecture (separate program and data buses). The 12-bit successive-approximation ADC includes sample-and-hold, selectable acquisition time, and operates in sleep mode with the RC oscillator. Brown-out Reset and Power-on Reset are integrated, reducing external component count. The -I suffix denotes industrial temperature grade (-40C to +85C); the /L suffix denotes the 44-pin PLCC (windowed ceramic in the /JW variant) package. Typical applications include industrial process control systems with multi-channel sensor acquisition, portable data loggers, automotive body and chassis subsystems (non-safety), instrumentation and measurement equipment, and educational/embedded training platforms. The 12-bit ADC and 33 I/O make it suitable for mixed-signal designs where moderate resolution and ample digital I/O are required. Design considerations include selecting the proper oscillator configuration (HS, XT, LP, RC), adding 0.1 uF decoupling near VDD pins, and routing analog and digital grounds to a single point. For high-ADC-resolution designs, place the analog supply trace away from switching nodes. OTP memory means firmware changes require a new device, so production code must be fully validated before programming. For in-circuit reprogrammability consider the flash-based PIC16F877 family as a modern alternative.
