PIC16C67T-20E/PT

PIC16C67T-20E/PT - 8-Bit 20MHz 14KB OTP MCU 44-TQFP | Microchip

The Microchip Technology PIC16C67T-20E/PT is an 8-bit CMOS EPROM/ROM-based microcontroller from the PIC16C family, featuring 14KB (8K x 14) of One-Time-Programmable (OTP) program memory, 368 bytes of RAM, and 33 digital I/O pins. It executes instructions at up to 20MHz (200ns instruction cycle) from a 4V to 6V supply and is housed in a 44-pin TQFP (10x10 mm) surface-mount package with tape-and-reel packaging. The "E" suffix denotes the Extended temperature grade (-40C to +125C) and the "T" denotes tape and reel. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (ROM/EPROM/Flash and RAM), and peripherals on one die. It belongs to the broader category of microcontrollers -> embedded processors -> semiconductors. PIC microcontrollers use a RISC architecture with a small, fixed instruction set optimized for deterministic real-time control in cost-sensitive applications. Unlike 32-bit Cortex-M parts, PIC16C devices target legacy industrial, automotive, and consumer designs where code size, power budget, and tool simplicity matter more than raw compute. Key features include 14KB OTP program memory, 368 bytes of RAM, three 8-bit timers (Timer0/Timer1/Timer2), a 10-bit multi-channel Analog-to-Digital Converter (ADC), Capture/Compare/PWM (CCP) modules, and serial peripherals including I2C, SPI, and USART. The device offers programmable brown-out reset (BOR), power-on reset (POR), watchdog timer (WDT), and an external oscillator interface. Peripherals such as PWM, ADC, and WDT make this MCU well-suited to closed-loop motor, power, and sensor-interface designs. The PIC16C67 architecture uses a Harvard-style separate code/data bus with a 14-bit instruction word and an 8-bit data path, achieving single-cycle instruction execution at the system clock rate. CMOS EPROM technology provides non-volatile program storage; the OTP windowed-EPROM variant enables prototype development with UV erasure, while the OT (one-time) variant is suited to volume production. Typical applications include industrial automation, consumer electronics, automotive body and chassis control modules, sensor interface boards, low-cost motor controllers, and legacy embedded systems requiring drop-in compatibility with the PIC16C6x family. Its 33 I/O pins and rich peripheral set support mixed-signal designs. When designing with this part, ensure a stable 4V-6V rail and a 20MHz external clock or ceramic resonator; insufficient decoupling on VDD/AVDD will degrade ADC accuracy. Because OTP memory cannot be reprogrammed in-circuit, plan for a flash-based PIC16F7x equivalent for prototypes and late-stage firmware revisions. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, supporting engineers in selecting and qualifying the PIC16C67T-20E/PT for both new designs and legacy maintenance.

PIC16C67T-20I/PQ

PIC16C67T-20I/PQ - 8-Bit 20MHz OTP MCU 14KB | Microchip

The Microchip Technology PIC16C67T-20I/PQ is an 8-bit RISC CMOS microcontroller from the PIC® 16C family, featuring 14KB (8K x 14) of One-Time Programmable (OTP) program memory, 368 bytes of data RAM, and 33 digital I/O pins. Housed in a 44-pin MQFP (Plastic Quad Flat Pack, 10x10 mm) surface-mount package with gull-wing leads, it operates from a 4.5V to 5.5V single supply at industrial temperature grade (-40C to +85C). An 8-bit microcontroller (MCU) is a small, single-chip computer built around an 8-bit data path that integrates a CPU, program memory, data RAM, and peripherals. The PIC16C6X family belongs to Microchip's mid-range 8-bit MCU hierarchy (MCU -> 8-bit MCU -> PIC16 family -> PIC16C6X mid-range), and the PIC16C67 sits at the top of this mid-range tier with the largest program memory and most I/O. The PIC16C67T-20I/PQ is specifically the industrial-temperature, 20 MHz speed grade offered in tape-and-reel ('T') MQFP packaging, distinguished from the PIC16C67-20I/PQ by its tape-and-reel orientation for high-volume SMT assembly lines. The PIC16C67T-20I/PQ's 35-instruction RISC architecture executes every instruction in a single 200 ns cycle (except program branches, which take two cycles), giving it deterministic throughput for real-time control. Key features include three 8-bit and one 16-bit timer/counter modules, two analog comparators, a USART, an SSP module supporting SPI and I2C (master/slave), a watchdog timer with its own on-chip RC oscillator, programmable code protection, and selectable oscillator modes (XT, HS, RC, LP, and external clock). Architecturally, the device uses a Harvard bus structure with separate program and data paths and a 14-bit-wide instruction word, allowing any register to be used directly as an accumulator. The 8-level hardware stack and 35 single-word instructions deliver high code density versus CISC 8-bit alternatives, while OTP program memory enables rapid prototyping of mature designs destined for masked-ROM production. Typical applications include industrial process control, motor-control front-ends, sensor signal conditioning, embedded communication bridges, and instrumentation requiring deterministic 8-bit processing. The 33 I/O pins also make it well suited for HVAC controllers, security panels, and white-goods appliance control boards where cost-sensitive MCU integration outweighs the need for in-system re-programmability. When designing with this part, note that the OTP variant cannot be erased or re-programmed in-circuit, so firmware verification must be completed before final programming - designers typically use a windowed (UV-erasable) PIC16C67JW or a Flash-based PIC16F877 for development and validation, then commit the locked firmware to the OTP PIC16C67T for production.

Key features of the PIC16C67T-20I/PT include: (1) wide 4.0V to 6.0V supply voltage range for industrial power rails; (2) fully static CMOS design enabling DC to 20 MHz operation; (3) on-chip peripherals including a 10-bit ADC, two 8-bit timers and one 16-bit timer, an enhanced USART, MSSP (I2C/SPI), and capture/compare/PWM modules; (4) industrial -40C to +85C operating temperature range (the "I" suffix); and (5) three serial communication interfaces (I2C, SPI, UART/USART) for sensor networks and inter-MCU buses. Architecturally, the PIC16C67 uses Harvard memory separation with a 14-bit instruction word and 8-bit data path. Its OTP EPROM cell enables one-time field programming with cost advantages over Flash, suitable for mature high-volume industrial products. The brown-out detect and watchdog timer support safety-critical applications where lockup recovery is mandatory. Typical applications include industrial control modules, motor drive controllers (using the PWM module), sensor interface boards (using the ADC and I2C/SPI peripherals), building automation, and embedded legacy replacement of older 8051-based designs. The 44-TQFP package provides ample I/O for keypad scanning, LCD drive, and multi-sensor acquisition. When designing with this part, note that OTP memory cannot be re-programmed - firmware bugs require a board swap, not a reflash. Use the PIC16F877 Flash equivalent for prototypes or low-volume runs, and reserve the PIC16C67T-20I/PT for cost-optimized high-volume production. This page consolidates distributor pricing, pin-compatible alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers source, evaluate, and integrate the PIC16C67T-20I/PT into legacy and new designs.

PIC16C71 parts have been superseded in many designs by flash-based PIC16F equivalents. The PIC16C71-04/SO delivers 200ns instruction execution at 4MHz clock input, true 8-bit arithmetic, hardware stack, watchdog timer, power-on reset, and the integrated 4-channel 8-bit ADC — a notable integration feature for a mid-1990s 8-bit MCU. Brown-out detection prevents code corruption at falling supply voltages, while the 13 I/O pins each carry individual TRIS direction control for mixed input/output bus designs. Device current is held below 2 mA typical at 5V/4MHz, and the part operates across the commercial 0C to +70C range (industrial -40C to +85C versions available separately). Typical applications include entry-level A/D conversion in automotive sensors, industrial control panels, appliance user interfaces, and low-cost consumer electronics. The on-chip ADC eliminates an external converter and reduces BOM cost in measurement and monitoring designs.

The Microchip PIC16C710-04I/P is an 8-bit RISC microcontroller in the PIC16C family, featuring a 4 MHz maximum clock speed, 896 bytes (512 x 14) of One-Time-Programmable (OTP) program memory, 36 bytes of data RAM, and 13 digital I/O pins, all housed in a 18-pin PDIP (Plastic DIP) through-hole package. It integrates a 4-channel 8-bit Analog-to-Digital Converter (ADC), making it a complete mixed-signal solution for entry-level embedded designs. What is a PIC microcontroller? A PIC (Peripheral Interface Controller) is a family of 8/16/32-bit RISC microcontrollers originally developed by Microchip Technology. Within the broader taxonomy, PIC16C devices are CMOS, OTP-based members of the 8-bit mid-range family, sitting between PIC10/12/16 baseline devices and PIC18 enhanced devices. They are widely deployed where deterministic behavior, low cost, and ease of programming are prioritized over raw performance. The PIC16C710's 4-channel 8-bit ADC lets designers read analog sensors directly without an external ADC, while its 13 I/O pins drive LEDs, switches, keypads, and low-speed communication lines. The '04' speed grade and 4 MHz oscillator/clock option target low-EMI applications, and the 'I' suffix indicates the industrial temperature range (-40C to +85C). The OTP program memory is one-time programmable - cost-effective for volume production but not re-programmable. Architecturally, the device uses Microchip's Harvard RISC architecture with separate program and data buses, 35 single-word instructions, and a 14-bit instruction word. The integrated ADC samples at a programmable rate and can be triggered from software or from a Timer overflow. Power management is handled via Sleep mode and a selectable oscillator, allowing current draw to drop below a few microamps for battery-friendly designs. Typical applications include appliance control panels, automotive sensor interfaces (basic), industrial control boards, and consumer electronics requiring analog input and minimal digital logic. The 'I/P' package (industrial temperature, 18-pin PDIP) is well suited for prototyping on breadboards and for through-hole production assemblies. The same die is also available in 18-pin SOIC and 20-pin SSOP packages for surface-mount designs. A key design consideration is OTP memory: firmware must be fully verified before programming because OTP cannot be erased or rewritten. Designers planning iterative development cycles should evaluate the Flash-based PIC16F equivalents (e.g., PIC16F716) for development, then move to the OTP PIC16C710 for production cost savings.

The OTP program memory is factory- or field-programmable one time only, which simplifies production for high-volume fixed-code applications while reducing per-unit cost compared to flash-based devices. The architecture combines a 14-bit instruction word with a separate 8-bit data path. A 2-level hardware stack, 8-bit timer/counter with programmable prescaler, watchdog timer with its own on-chip RC oscillator, and a power-on reset (POR) circuit are all integrated. Brown-out protection and a power-saving SLEEP mode reduce system-level current draw for battery-operated use cases. Typical applications include entry-level A/D signal conditioning in automotive sensors, white-goods control boards, simple industrial monitoring loops, and consumer-appliance user-interface controllers. The 4-channel ADC is well-suited to multi-sensor reading, while the small 18-SOIC footprint supports compact PCB layouts.

The PIC16C710 uses a modified Harvard architecture with separate program and data buses, allowing simultaneous instruction fetch and operand access. The OTP program memory is field-programmable, meaning each device is programmed once and cannot be electrically erased; this makes the part ideal for low-to-medium volume production where flash reprogrammability is not required. The integrated 8-bit ADC uses successive-approximation conversion with a configurable clock source, supporting both ratiometric measurements with VDD as the reference and absolute measurements using an external reference. Typical applications include automotive sensor interface nodes, industrial control front-ends, appliance control boards, and consumer product analog front-ends. Designers commonly pair the PIC16C710 with external op-amps for signal conditioning, EEPROM for non-volatile parameter storage, and discrete RS-232 or RS-485 transceivers for legacy communication links. The 20 MHz top clock speed provides 5 MIPS of throughput, ample for polling-based control loops and slow-protocol UART links. When designing with this device, note that OTP programming means firmware cannot be updated in the field; budget time for one-time prototypes using the UV-erasable PIC16C71 (windowed CERDIP) variant for development, then move to the PIC16C710-20/SS for production. Provide adequate decoupling near the VDD pin and route the ADC analog inputs away from high-frequency digital traces to preserve conversion accuracy.

PIC16C710T-04/SS

PIC16C710T-04/SS - 4MHz 8-bit OTP MCU with 4-ch 8-bit ADC | Microchip

The Microchip PIC16C710T-04/SS is a CMOS, fully-static, OTP-based 8-bit RISC microcontroller in a 20-pin SSOP package (Tape & Reel), delivering 4 MHz maximum clock speed, 896 bytes of OTP program memory (512 x 14), 36 bytes of RAM, and 13 digital I/O pins. It integrates a 4-channel, 8-bit Analog-to-Digital converter and executes instructions in 200 ns using Microchip's PIC16C mid-range core. An 8-bit PIC microcontroller is a single-chip computer built around a RISC architecture that uses a fixed instruction width and a Harvard memory structure (separate program and data buses). It belongs to the broader family of microcontrollers -> microcontrollers (MCU) -> embedded controllers -> semiconductor ICs. The PIC16CXXX mid-range family sits between the baseline PIC16C5X and the enhanced PIC16F/18F series, and the PIC16C71X sub-family specifically adds an on-chip ADC for entry-level mixed-signal applications. Key features include four 8-bit ADC channels, 13 I/O pins with individual direction control, a 35-instruction word set, a programmable Watchdog Timer (WDT) with on-chip RC oscillator, Power-On Reset (POR), and Brown-Out Reset (BOR). The device operates from 4.0 V to 6.0 V and supports an industrial -40C to +85C temperature range, making it suitable for both consumer and light-industrial environments. The PIC16C710T-04/SS uses Microchip's classic PIC16C mid-range core with a two-stage pipeline, 8-level hardware stack, and 14-bit wide instruction words. Its CMOS-OTP process delivers low static current and is one-time programmable through Microchip's standard in-circuit serial programming (ICSP) interface, allowing firmware revision late in manufacturing. Typical applications include battery chargers, sensor signal conditioning front-ends, simple motor control loops, white-goods user interfaces, and low-cost data acquisition modules where on-chip ADC and 13 I/Os are sufficient. Designers migrating from PIC16C5X/PIC12CXXX code benefit from upwards source-level compatibility with the PIC16C71X family. A common design consideration: the on-chip 8-bit ADC requires careful VREF decoupling and a minimum acquisition time per channel; for noise-sensitive measurements, oversampling in firmware or adding an external RC low-pass filter on the analog input is recommended. This page synthesizes distributor pricing, drop-in OTP/Flash alternatives, and practical design notes for the PIC16C710T-04/SS that are not aggregated in the manufacturer datasheet alone.

PIC16C710T-04E/SO

PIC16C710T-04E/SO - 4MHz 8-bit OTP MCU with ADC | Microchip

The Microchip Technology PIC16C710T-04E/SO is an 8-bit CMOS RISC microcontroller from the PIC16C family, featuring 896 bytes (512 x 14) of One-Time-Programmable (OTP) program memory, 36 bytes of RAM, and 13 I/O pins, housed in an 18-pin SOIC wide-body package supplied on tape-and-reel. It executes one instruction per 200 ns cycle at a 4 MHz oscillator frequency, providing 5 MIPS throughput from a 5 V supply. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and peripheral set on one die. The PIC16C architecture is a Harvard-type RISC core with 35 single-word instructions and is upwards compatible with PIC16C5X and PIC12CXXX devices. Positioned in the broader taxonomy, the PIC16C710 belongs to the mid-range PIC family, sitting between baseline (PIC10/12/16C5X) and enhanced mid-range (PIC16F) MCUs, and is a member of the power management and embedded control semiconductor category. Key features include four channels of 8-bit Analog-to-Digital conversion with on-chip sample-and-hold, a programmable code-protection bit, an internal RC oscillator option, a Watchdog Timer with its own on-chip RC oscillator, and a power-saving SLEEP mode. The brown-out-reset is not present on this OTP silicon, so designers needing BOR should migrate to the PIC16F710 flash sibling. The 18-SOIC wide-body footprint keeps the part compatible with hand-soldered prototypes as well as high-volume SMT lines. Architecturally, the device uses a 14-bit instruction word with separate program and data buses (Harvard), giving deterministic single-cycle execution except for branch instructions that take two cycles. The 4-channel 8-bit ADC can digitize analog sensor inputs directly, removing the need for an external ADC in simple data-acquisition applications. Typical applications include battery chargers, consumer white goods, HVAC controls, simple sensor interfaces, and low-cost motor-control signal conditioning. With 4 MIPS at 5 V and only 13 I/O, it is well matched to space-constrained, low-pin-count embedded designs. When designing with the PIC16C710T-04E/SO, ensure that the MCLR reset network (typically 10 kohm pull-up to VDD) is present and that decoupling uses a 0.1 uF ceramic capacitor placed within 5 mm of the VDD pin. Note that this OTP variant can be programmed only once; for prototypes requiring firmware iteration, the PIC16F710 in the same 18-SOIC footprint with flash memory is recommended. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet alone, giving procurement and firmware engineers a single reference for sourcing and substituting the PIC16C710T-04E/SO.
