PIC16C662-20E/PQ - 8-Bit 20MHz 7KB OTP MCU 44-MQFP | Microchip

The Microchip Technology PIC16C662-20E/PQ is an 8-bit EPROM/OTP-based CMOS microcontroller delivering 7KB (4K x 14) of one-time-programmable program memory in a 44-pin Metric QFP (MQFP) surface-mount package. The device operates from DC to 20 MHz and integrates 33 digital I/O lines plus analog comparators, positioning it for embedded control applications that need flexible I/O and onboard analog functions. What is an OTP microcontroller? An OTP (One-Time-Programmable) microcontroller contains EPROM-based program memory that can be written once by a programmer and then behaves like ROM for the rest of its operating life. Compared with FLASH MCUs, OTP parts offer lower unit cost in high-volume production and stronger bit-cell retention because the programming is permanent. Compared with masked-ROM parts, OTP avoids the mask NRE charge and shortens development cycles, which is why PIC16C-series devices were historically used in pre-production and small/medium production runs. Key features of the PIC16C662 include 33 I/O pins, a 20 MHz operating frequency (50 ns instruction cycle), integrated analog comparators, and the standard PIC16C peripheral set (timers, USART, capture/compare/PWM). The PIC16C662 belongs to the PIC16C6x mid-range family, sharing the same 14-bit instruction set and core architecture as other 16C6x devices, which simplifies firmware migration across family members. From an architectural perspective, the device uses a RISC-style Harvard core with separate program and data paths, allowing instruction fetch and operand access in the same cycle. The 20E temperature-range suffix specifies an extended operating range of -40C to +125C, while the /PQ suffix denotes a 44-pin Metric Plastic QFP (MQFP) package suitable for surface-mount assembly. Typical applications include industrial control panels, appliance controllers, automotive body and chassis subsystems, motor-drive front-end logic, smart sensors, and instrumentation front-ends. The integrated analog comparators simplify designs that previously required a separate op-amp or comparator IC. A key design consideration is that the PIC16C662 is an OTP part - firmware revisions require a new silicon spin, so the development cycle should converge to a stable firmware image before volume ramp. The extended temperature grade also makes the device suitable for under-hood automotive and outdoor industrial deployments.

It integrates on-chip analog comparators and a 14-bit instruction set optimized for low-power embedded control, operating from a 4V to 6V supply typical of legacy 5V industrial designs. The device also provides multiple timer modules, a watchdog timer, and up to 33 digital I/O pins for general-purpose interfacing. An 8-bit OTP (One-Time Programmable) microcontroller is a single-chip computer built around an 8-bit data path, with non-volatile program memory that can be written only once during production programming. The PIC16C662 belongs to the PIC16Cxx family of microcontrollers -> 8-bit MCU -> microcontroller -> embedded computing IC. This category sits beneath 16-bit and 32-bit MCU families in the embedded hierarchy and remains favored in cost-sensitive, deterministic-control applications where bit-manipulation efficiency and predictable interrupt latency matter more than raw compute throughput. Key features include 4K x 14 words of program memory (7KB), 176 bytes of data RAM, two analog comparators with programmable reference, three timer modules (Timer0, Timer1, Timer2), a watchdog timer with on-chip RC oscillator, and an operating temperature range of -40C to +125C (extended 'E' grade). The 14-bit wide instruction word allows single-cycle instructions for most arithmetic and logical operations, and the Harvard bus architecture separates program and data paths to improve throughput. The part supports in-circuit serial programming (ICSP) and operates across 4.0V to 6.0V input voltage. The PIC16C662 uses a RISC architecture with a fixed instruction set of 35 single-word/14-bit instructions, each typically executing in one instruction cycle (4 clock periods). Internal oscillator options include an RC mode for low-cost designs and a crystal/ resonator mode for precision timing. The device's CMOS process and sleep mode reduce quiescent current to microampere levels, making it suitable for battery-backed instrumentation. Industrial temperature grading and ceramic-package-friendly thermal performance support deployment in factory automation, automotive subsystems, and process control. Typical applications include industrial motor control loops, sensor signal conditioning with on-chip comparators, appliance control boards, automotive body electronics (pre-CAN era), security system panels, and general-purpose 5V embedded control where flash-based MCUs are unnecessary. The two analog comparators make it well-suited for threshold detection on thermistor bridges, photocells, or current-sense amplifiers without needing an external op-amp. When designing with this device, note that OTP memory cannot be reprogrammed in the field; for in-system firmware updates, migrate to the PIC16F662 flash equivalent. Place a 0.1uF decoupling capacitor close to VDD and VSS, and reserve the MCLR pin configuration for the system's required reset topology (internal or external).

The '/L' suffix denotes the PLCC package, while the 'T' indicates Tape & Reel packaging, and '-04' specifies the 4 MHz speed grade. What is an OTP microcontroller? An OTP MCU is a type of embedded controller whose program memory can be written only once using a device programmer, after which the contents are permanent (non-erasable). It belongs to the broader family of microcontrollers, which themselves fall under the hierarchy of microprocessors → computing ICs → integrated circuits. OTPs occupy a middle ground between mask-ROM MCUs (lowest unit cost at very high volumes) and flash-based MCUs (re-programmable, higher unit cost), making them popular for cost-sensitive, mature production designs where firmware is stable and field updates are not required. Key features include 35 single-cycle instructions (200 ns except for program branches which take two cycles), a 14-bit instruction word, integrated peripherals such as Brown-out Detect/Reset (BOR), Power-on Reset (POR) and Watchdog Timer (WDT), and a commercial operating temperature grade. The PIC16C662 also provides multiple interrupt sources and a programmable timer/counter subsystem. As a member of the mid-range PIC16C family, it is source- and object-code compatible with many siblings, easing migration within the platform. Typical applications include appliance controls, industrial automation modules, HVAC interface boards, automotive body controllers (non-safety subsystems), security keypads, and embedded user-interface controllers where a stable firmware image, deterministic execution, and low unit cost are priorities. The 33 I/O pins allow direct drive of LED indicators, keypads, and discrete logic. When designing with this part, verify that your firmware has been fully validated before committing to OTP programming because field updates are impossible. The OTP window also requires a specialized programmer that applies programming pulses above VDD; check the Microchip device programmer documentation for compatibility. The 4 MHz speed grade offers the lowest cost; consider the -20 (20 MHz) variants if higher throughput is required.

The 16C-series parts use a Harvard RISC core with a 14-bit-wide instruction word and 8-bit data path, giving a compact code footprint for low-to-moderate complexity control loops. PIC16C6xx devices are commonly deployed in industrial and commercial embedded systems where stable, OTP-based code storage is acceptable and a 44-pin PLCC package is preferred for through-hole or socketed designs. Key features of the PIC16C662T-10/L include 192 bytes of data RAM, a 14-bit instruction word, multiple timer/counter peripherals, a synchronous serial port (SSP) supporting SPI/I2C master and slave modes, and a parallel slave port. The device provides 33 digital I/O pins and supports interrupt-driven control with a programmable watchdog timer. The OTP program memory allows one-time programming in production, providing robust code retention without external EEPROM in many applications. The PIC16C662 architecture uses a two-stage pipeline with a single accumulator and W-register working scheme; the 14-bit instruction word includes literal data and control fields, allowing most instructions to execute in one instruction cycle (four clock periods) at 10 MHz. Built-in brown-out reset and power-on reset circuitry improves system reliability in industrial environments where supply rails may be noisy or slowly rising. Typical applications include industrial control panels, appliance controllers, motor drive interface boards, instrument front-ends, security alarm panels, and legacy embedded systems migrating from 16C-series designs. The wide commercial operating range (0C to +70C) and PLCC socket compatibility make this part a drop-in fit for established production lines. The OTP memory is well suited to high-volume production runs where code has stabilized and field firmware updates are not required. When designing with the PIC16C662T-10/L, pay attention to oscillator configuration (XT/HS/RC modes supported), ensure the PLCC socket is keyed correctly, and reserve an additional flash-based PIC16F part as a backup option if future firmware revisions are anticipated. The commercial temperature grade makes this variant better suited to benign environments than the -I industrial variant.

The "T" suffix indicates tape-and-reel packaging, the "/PQ" suffix denotes the Metric Quad Flat Pack (MQFP-44) variant, and the "-10" speed grade specifies a 10 MHz oscillator. It is built on a CMOS process and integrates Brown-Out Detect (BOD), two analog comparators, Power-On Reset (POR), timers, and a Watchdog Timer (WDT). An 8-bit microcontroller (MCU) is a programmable computing engine that executes instructions on 8-bit data paths and serves as the embedded brain of consumer appliances, industrial controllers, and legacy automotive subsystems. MCUs sit below microprocessors in the silicon hierarchy and above discrete logic, integrating CPU core, non-volatile program memory, working RAM, and peripherals into a single die. The PIC16C family targets cost-sensitive applications where OTP programmability, deterministic instruction timing, and small footprint are valued over in-system re-programmability. Key features of the PIC16C662T-10/PQ include 22 I/O pins with individually programmable direction, a 14-bit instruction word, a Harvard architecture with separate program and data buses, and a wide operating voltage range typical of the PIC16C series. The device is well-suited to applications that require moderate code density (4K words), low power consumption, and analog signal conditioning via on-chip comparators. Typical applications include appliance control boards, industrial sensor interfaces, security and access-control panels, HVAC actuators, and legacy embedded products. Designers typically pair it with external EEPROM or serial ADC peripherals when non-volatile data storage or higher-resolution analog input is required. When designing with the PIC16C662T-10/PQ, ensure the OTP window is masked if code security is required, and account for the 10 MHz oscillator ceiling when selecting crystal or resonator components. Because this is an OTP device, firmware verification must be performed on-window or on pre-programmed parts before final commit; consider a flash-based PIC16F equivalent if in-field firmware updates are required.

It operates from a 5V supply, supports a 10 MHz maximum clock frequency in the -10 speed grade, and is supplied on tape and reel for high-volume assembly. An 8-bit microcontroller (MCU) is a small computer-on-a-chip that integrates a CPU, non-volatile program memory, working RAM, digital I/O, and one or more peripherals such as timers, capture/compare, ADC, or communication interfaces into a single IC. PIC16-series MCUs use a Harvard RISC core with a 14-bit instruction word and a fixed program/data bus architecture, positioning them within the broader hierarchy of microcontroller -> embedded controller -> semiconductor device, and historically targeting low-power deterministic real-time control applications. Key features of the PIC16C662T-10/PT include 7 KB of on-chip OTP EPROM, 128 bytes of RAM, multiple timers, capture/compare/PWM peripherals, a 10 MHz maximum operating frequency, and an industrial-relevant operating temperature range. The 44-TQFP package provides 33+ general-purpose I/O pins, suitable for parallel display driving, keypad scanning, and multi-channel sensor interfaces. The OTP memory enables low-cost prototyping with a mature toolchain. From an architecture perspective, the device uses a Harvard RISC core with separate program and data buses, allowing instruction fetch and data access to occur in the same cycle. The 14-bit instruction set is fixed-width for deterministic timing, and integrated brown-out reset, watchdog timer, and power-on reset support robust embedded operation. The OTP memory is one-time programmable in production units and is windowed-erasable in ceramic-DIP variants of the PIC16C662 family. Typical applications include industrial control panels, instrument front panels, low-cost keypad/display interfaces, appliance controllers, and legacy embedded products that were designed around the PIC16C family during the 1990s. Its deterministic core and rich I/O set make it well suited to real-time bit-banging, multi-channel sensor multiplexing, and slow-bus peripheral bridging. When designing with this part, note that OTP memory cannot be re-programmed in-circuit, so firmware validation must be completed on a windowed (JW) or flash-equivalent (PIC16F) variant before committing to OTP. Decoupling must follow Microchip's recommended 100 nF near each VDD/VSS pair, and unused I/O should be left as outputs-low or inputs with weak pull-ups to minimize ICC.

The device operates from a 4.0V to 6.0V supply and is rated for a maximum clock frequency of 10 MHz, with the "-10" speed designation confirming 10 MHz operation across the full VDD range. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (ROM/EPROM/Flash/OTP), data RAM, I/O peripherals, and timers onto one die. PIC microcontrollers use a Harvard RISC architecture with a small, fixed instruction set optimized for deterministic, single-cycle execution (excluding branches). They sit within the broader category of microcontrollers -> embedded processors -> semiconductors. OTP variants like the PIC16C662 are typically chosen for low-to-medium volume production where the cost of Flash reprogrammability is not justified, but field-programmability during prototyping is still required. Key features of the PIC16C662T-10E/PQ include integrated analog peripherals (two on-chip comparators and an 8-bit ADC reference per the PIC16C66x family), Brown-Out Detect (BOD) and Power-On Reset (POR) for robust supply supervision, a Watchdog Timer (WDT) for runaway code recovery, and a programmable 8-bit prescaler shared between Timer0 and the WDT.

The Microchip Technology PIC16C662T-10I/PQ is an 8-bit EPROM/OTP-based CMOS microcontroller from the PIC16C family, delivering 7KB (4K x 14) of one-time-programmable program memory in a 44-pin MQFP (PQ) package measuring 10x10 mm. It runs at a maximum clock frequency of 10 MHz, is built around a RISC-style Harvard architecture, and is qualified for the industrial temperature range (-40C to +85C). The PIC16C662 is one of the original PIC microcontroller families that established Microchip's dominance in 8-bit embedded design. A microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (ROM/EPROM/Flash/OTP), data memory (RAM), and programmable I/O peripherals into one device. 8-bit MCUs sit at the entry point of the embedded hierarchy: microcontroller -> embedded controller -> system-on-chip -> semiconductor. The PIC16C family in particular uses a 14-bit instruction word (rather than 12-bit on PIC16F baseline or 16-bit on PIC18), which makes it well-suited for compact code density in cost-sensitive designs. Key differentiating features of the PIC16C662T-10I/PQ include its 7KB OTP program memory, integrated analog peripherals for mixed-signal embedded designs, industrial-grade -40C to +85C operating range, and 33 programmable digital I/O lines. The 'T' suffix denotes tape-and-reel packaging for high-volume assembly, while 'I' specifies industrial temperature grade and 'PQ' indicates the 44-pin MQFP package. The '10' speed grade designates the 10 MHz maximum clock frequency. Architecturally, the device uses a Harvard structure with separate program and data buses, a 14-bit wide instruction word, and a small register-based file architecture that lets most instructions execute in one instruction cycle (four clock periods). This gives roughly 5 MIPS sustained throughput at 10 MHz - modest by modern standards but sufficient for the appliance, automotive aftermarket, and industrial control applications where the PIC16C662 is typically deployed. OTP (one-time-programmable) memory allows factory or pre-production programming, making the device cost-effective for mature, finalized designs. Typical applications include appliance control boards, motor control front-ends, security panel logic, simple human-machine interface controllers, and industrial sensor signal conditioning. The wide industrial temperature range makes it suitable for outdoor or factory-floor equipment, while the analog peripheral integration removes the need for an external ADC in many designs. Program development uses MPLAB and the PIC16C instruction-set tools, which remain compatible with current MPLAB X IDE. When designing with the PIC16C662T-10I/PQ, note that OTP memory cannot be erased or rewritten - this part is intended for finalized firmware and high-volume production. Engineers should also verify the available in-circuit debugger/signature unit support, since the PIC16C family uses a parallel programming interface rather than the modern ICSP used by PIC16F/PIC18 devices.

The 44-MQFP PQ package gives 33 general-purpose I/O lines organized across five ports (PORTA through PORTE), enabling direct connection to keypads, LCDs, and external peripherals without external glue logic. The PIC16C662 uses Microchip's classic RISC-like Harvard architecture, where separate program and data buses let the CPU fetch an instruction and access data in a single cycle. OTP memory is programmed once with a device programmer and cannot be erased, which lowers per-unit cost relative to UV-erasable windowed EPROM parts and makes the part well suited to mature, code-stable designs rather than iterative development. Typical applications include industrial control front panels, appliance user-interface controllers, HVAC thermostat boards, security-system keypads, and embedded sensor hubs in automotive and aerospace systems. The wide operating temperature range also supports outdoor and factory-floor deployments. When designing with this part, note that OTP memory cannot be re-programmed in-circuit; prototype and debug with a windowed or Flash equivalent (e.g., PIC16F662 in the same 44-pin footprint) before committing to the production OTP order. Brown-out reset voltage and oscillator configuration are fuse-selected at program time.

PIC16C66T-04E/SO - 8-Bit 4MHz 14KB OTP MCU, 28-SOIC | Microchip

The Microchip Technology PIC16C66T-04E/SO is an 8-bit RISC CMOS microcontroller belonging to the PIC® 16C family, delivering 14 KB (8K x 14) of One-Time Programmable (OTP) program memory and 368 bytes of data RAM, with a 4 MHz maximum clock input and 5V (4.5V–5.5V) supply, all in a 28-pin SOIC wide-body package. A PIC microcontroller is a Harvard-architecture, RISC-based 8-bit device that executes one instruction per cycle (except program branches, which take two), giving deterministic timing and very low interrupt latency. The PIC16C6X sub-family in particular introduced an enhanced instruction set, 14-bit wide instruction word, 8-level hardware stack, and on-chip peripherals such as capture/compare/PWM and an analog comparator. These MCUs sit within the broader power-management/embedded-control hierarchy: microcontroller -> embedded processor -> digital IC -> semiconductor, and are programmed in C or assembly through Microchip's MPLAB X toolchain. Key features of the PIC16C66T-04E/SO include a 33 I/O pin count (22 strong I/O plus supporting pins), a wide 4.5 V to 5.5 V supply range, automotive temperature grade ('E' suffix indicates -40 °C to +125 °C extended), 200 ns single-cycle instruction time at 20 MHz, and CMOS low-power operation. It is also built on Microchip's mature OTP process, which trades in-system reprogrammability for very low per-unit cost in volume production runs. The on-chip peripheral set includes three timers, a USART, a synchronous serial port (SSP) supporting SPI and I²C, an 8-bit analog-to-digital converter with up to 8 channels, and a capture/compare/PWM module. This integration lets one PIC16C66 replace a discrete MCU plus several support ICs, simplifying PCB layout and BOM cost. Typical applications include industrial control logic boards, automotive body and chassis ECUs, appliance motor control, and legacy embedded subsystems designed before flash-based PICs (PIC16F family) became standard. Its OTP memory makes it especially suited for high-volume, code-stable products where firmware never needs field updates. Designers should note that the '04' speed grade is 4 MHz (versus the '10' and '20' variants that scale to 20 MHz) and the 'E' temperature grade is the -40 °C to +125 °C extended range, not the -40 °C to +85 °C industrial range (which would be 'I'). This page consolidates distributor pricing, pin-compatible drop-in alternatives in the PIC16C66 family, and design notes distilled from the manufacturer datasheet and Microchip cross-reference database - information not aggregated on any single distributor product page.

PIC16C66T-04I/SO

PIC16C66T-04I/SO - 8-Bit 4MHz 14KB EPROM MCU 28-SOIC | Microchip

The Microchip Technology PIC16C66T-04I/SO is a 8-bit RISC CMOS microcontroller based on the PIC16C core, featuring 14KB of one-time-programmable (OTP) EPROM program memory and 368 bytes of data RAM, housed in a 28-pin SOIC wide-body package supplied on Tape & Reel. The device operates from a 4.5V to 5.5V supply and is rated for a maximum clock frequency of 4 MHz, with an internal architecture supporting 22 digital I/O lines. A PIC microcontroller (Programmable Integrated Circuit) is a family of low-cost, high-performance, fully-static 8-bit microcontrollers built on a RISC (Reduced Instruction Set Computing) architecture, in the broader category hierarchy of microcontroller -> embedded processor -> semiconductor IC. The PIC16C6X family uses only 35 single-word instructions to learn, with all instructions executing in a single cycle except program branches (two-cycle), giving a deterministic instruction throughput. The 'C' suffix denotes the original EPROM-based PIC16 family, distinguishing it from later flash-based PIC16F parts. Key features include 14KB EPROM program memory (8K x 14-bit words), 368 bytes of data RAM, 22 digital I/O pins, integrated synchronous serial port (SSP) supporting SPI and I2C, an addressable USART, three 8-bit timer/counters plus one 16-bit timer/counter with capture/compare/PWM, an 8-bit analog-to-digital converter (ADC) on select family members, and a watchdog timer with on-chip RC oscillator. The 'T' suffix indicates Tape and Reel packaging, while the 'I' suffix indicates the industrial temperature grade of -40C to +85C. The 28-pin SOIC wide-body (7.50 mm) package is a surface-mount plastic outline with a lead pitch of 1.27 mm, and the device is qualified for industrial operating environments. The PIC16C66T-04I/SO uses a Harvard architecture with separate program and data buses, which allows simultaneous fetch of an instruction and access of a data operand, maximizing throughput at the 4 MHz clock input. Typical applications include industrial control systems, automotive body and chassis electronics, low-power consumer devices, sensor interface front-ends, and embedded control boards where a small package count and well-documented peripheral set are required. The on-chip peripherals (USART, SSP, timers, ADC) reduce external component count for cost-sensitive designs. When designing with this part, note that the 4 MHz rating reflects the maximum oscillator input; at this clock most instructions execute in 1 microsecond, and at 5V supply the device typically draws under 20 mA active. Ensure the MCLR reset, oscillator, and power pins are properly decoupled per the Microchip PIC16C6X datasheet to avoid spurious resets or oscillator start-up issues. This page synthesizes distributor pricing, drop-in and same-family alternatives, and practical design notes not found in a single source on the manufacturer datasheet, helping engineers evaluate and source the PIC16C66T-04I/SO efficiently.
