PIC16C64AT-10I/PQ - 8-Bit PIC MCU 3.5KB OTP 33 I/O | Microchip
MPN: PIC16C64AT-10I/PQ ✗ اختتامِ زندگیPIC16C64AT-10I/PQ جائزہ
What is a PIC16C64A? The PIC16C64A belongs to the PIC16C6X mid-range family of 8-bit microcontrollers, descended from the original PIC16C5X baseline. These MCUs use a RISC (Reduced Instruction Set Computer) architecture with only 35 single-word instructions to learn, where most instructions execute in one instruction cycle. As a Harvard-architecture device, the PIC16C64A has separate program and data buses, allowing simultaneous instruction fetch and data access. It sits in the microcontroller hierarchy as: microcontroller -> embedded controller -> 8-bit MCU -> PIC mid-range -> PIC16C6X family.
Key features of the PIC16C64AT-10I/PQ include a 10 MHz maximum clock, 200 ns instruction cycle, three hardware timers (Timer0, Timer1, Timer2), a USART module for asynchronous serial communication, and a parallel slave port. The T suffix denotes tape-and-reel packaging, while I specifies the industrial temperature grade. The PQ suffix indicates the 44-pin Metric Quad Flat Pack (MQFP) gull-wing surface-mount package.
This device uses EPROM/OTP program memory rather than Flash, meaning code is written once and cannot be electrically erased. This makes the part well suited for high-volume production where firmware is finalized, but limits prototyping use compared to Flash-based PIC16F equivalents. CMOS technology provides low power consumption with typical applications drawing only a few milliamps.
Typical applications include industrial control systems, motor drive front-ends, sensor interfacing, automotive body electronics, and embedded control panels where a 5 V-tolerant interface to external peripherals is required. The 33 I/O pins comfortably drive keypads, LED arrays, LCD modules, and small relay or solenoid loads.
When designing with this part, note that OTP memory precludes in-system firmware updates. For development, engineers should prototype on a Flash-equipped sibling (PIC16F64A-equivalent or PIC18 baseline) and migrate to the OTP PIC16C64A once firmware is frozen.

Industrial Control Systems
The PIC16C64AT-10I/PQ fits industrial control applications through its 33 I/O pins capable of driving keypads, LED indicators, and small relays. The 3.5KB OTP program memory accommodates mid-complexity control logic for PLCs and process controllers. At 10 MHz with a 200 ns instruction cycle, it executes PID loops and state machines fast enough for conveyor control and machine automation. Industrial -40C to +85C temperature rating ensures operation in factory environments. Companion parts include the PIC16C64A-10I/PQ (tube version) and ATMEGA328P-PU for new designs.

Motor Drive Front-End Controllers
The PIC16C64AT-10I/PQ serves as the control front-end in motor drive systems, generating PWM signals and monitoring feedback from Hall sensors or encoders. The 3 timers (Timer0, Timer1, Timer2) provide dedicated PWM generation, input capture, and timing functions needed for brushless DC motor commutation. 5 V I/O compatibility allows direct interfacing to gate driver ICs and current-sense amplifiers. With 33 I/O pins, it manages direction control, brake signals, and fault interlocks. Recommended companions are PIC16F877A (Flash migration path) and gate drivers like IR2104.

Sensor Interfacing Hubs
The PIC16C64AT-10I/PQ aggregates signals from multiple sensors in industrial monitoring systems. The 33 I/O pins accept digital inputs from proximity switches, limit switches, and digital temperature sensors. The USART (SCI/SPI) interfaces to digital sensor networks, while the parallel slave port allows high-speed data transfer from external ADCs. The 10 MHz CPU executes sensor-reading routines with predictable timing. The 5 V supply matches legacy industrial sensor outputs. Companion options include the PIC16C63A-20I/SO for lower-pin-count designs and external ADC128S102.

Automotive Body Electronics
The PIC16C64AT-10I/PQ controls non-safety automotive body functions such as interior lighting, power windows, and seat controllers. The 33 I/O drive LEDs and small DC motor loads through external MOSFETs. The 3.5KB OTP memory holds fixed body-control firmware with no in-field updates needed. Industrial temperature range -40C to +85C covers most cabin environments, though under-hood applications would require the PIC16C64AT-10E/PQ extended-temperature variant. The 5 V supply integrates with automotive 12 V systems via regulators. Companion chips include the PIC16C62A-04I/SO and VIPer12A SMPS controller.

Embedded Control Panels
The PIC16C64AT-10I/PQ powers HMI control panels with keypads, LCD displays, and status LEDs. The 33 I/O scan a 4x4 matrix keypad (8 pins), drive a character LCD in 4-bit mode (6 pins), and illuminate status LEDs while monitoring switch inputs. The 3.5KB OTP holds menu navigation and control logic, while the USART relays commands to a host controller or PLC. The PIC16C64AT-10I/PQ's industrial temperature rating ensures reliability in shop-floor panels. Recommended companions include HD44780-compatible LCDs and PIC16C642-04I/SO for smaller displays.

Legacy Embedded Systems Maintenance
The PIC16C64AT-10I/PQ is the OEM replacement part for legacy products originally designed around the PIC16C64A family. The OTP memory matches original production firmware, allowing direct PCB replacement without firmware porting. The MQFP-44 package maintains the original PCB footprint in equipment still in field service. With this part being obsolete since the early 2000s, distributors carry diminishing stock, making last-time-buy planning critical for ongoing service contracts. Sourcing channels include broker inventory and franchised distributor overstock.

ڈیزائن نوٹس
The PIC16C64AT-10I/PQ uses EPROM/OTP program memory that cannot be electrically erased. Code bugs discovered after programming require physical replacement of the MCU. During development, prototype with a Flash-based sibling such as PIC16F877A (similar peripheral count, 40-pin PDIP) or PIC16F917-I/PT (TQFP-44 footprint match) to enable in-circuit reprogramming. Migrate to PIC16C64AT-10I/PQ only after firmware is fully validated and frozen for production.
The MQFP-44 package has 0.8 mm lead pitch and requires careful PCB layout. Place decoupling capacitors (100 nF ceramic + 10 uF tantalum) within 5 mm of Vdd pins 18, 20, and 40. Connect all Vss pins (11, 19, 31) to a ground plane with multiple vias for thermal dissipation. The MCLR pin (42) requires a 10 kohm pull-up to Vdd; add a 100 nF capacitor to ground for noise immunity. Crystal oscillator traces should be short and guarded by ground on both sides.
The PIC16C64AT-10I/PQ operates from a 5 V supply, and its I/O pins are TTL-compatible but not 5 V-tolerant when used as analog inputs. Use the AN0-AN7 analog inputs within the Vdd-Vss range; voltages above Vdd may damage the ADC multiplexer. The USART pins (RC6/RC7) drive CMOS/TTL levels directly; for RS-232 communication add a MAX232 or similar level shifter. The parallel slave port (PORTD) is a high-speed data bus - keep traces under 50 mm and add 33 ohm series termination for cables longer than 100 mm.
