MPN: PIC17C762T-16I/L ✗ סוף ייצורPIC17C762T-16I/L סקירה
An EPROM-based microcontroller is a programmable single-chip computer whose program memory uses Erasable Programmable Read-Only Memory that can be erased by UV exposure and re-programmed, supporting prototype and pre-production development before mask-ROM commit. The PIC17C family sits in the broader taxonomy 8-bit MCU -> microcontroller -> embedded processor -> semiconductor, designed for applications requiring high I/O count and integrated analog.
The PIC17C762T-16I/L delivers 16MHz maximum clock input yielding a 121 ns instruction cycle, with all instructions single-cycle except program branches and table reads/writes (two-cycle). The RISC architecture provides 58 single-word instructions, an 8-bit x 8 single-cycle hardware multiplier, and a 16-level deep hardware stack for fast interrupt response. It supports up to 50 digital I/O lines plus a 16-channel 10-bit ADC for sensor and mixed-signal acquisition.
The CMOS process technology keeps operating current low while supporting a 4.5V to 5.5V supply. Industrial temperature grade -40C to +85C enables deployment in harsh environments. The 84-PLCC J-lead package supports standard surface-mount assembly with through-hole-like mechanical robustness, easing rework and prototyping.
Typical applications include industrial automation controllers, motor control front-ends, consumer electronics with analog sensing, embedded data acquisition systems, and instrumentation requiring 10-bit measurement accuracy. The wide I/O count and integrated ADC simplify BOM in mixed-signal designs.
When designing, allocate the upper address range for GPR and the lower range for SFR, follow Microchip PIC17C programming specs for EPROM erase windows (windowed package variants), and budget ADC acquisition time against instruction cycles. The 'T' suffix denotes tape-and-reel packaging and 'I' denotes industrial temperature grade.

יישומים טיפוסיים
PIC17C762T-16I/L מתאים עבור 6 יישוםs: Industrial Automation Controllers, Motor Control Front-Ends, Consumer Electronics with Analog Sensing, Embedded Data Acquisition Systems, Instrumentation and Test Equipment, HVAC and Building Control.
Industrial Automation Controllers
The PIC17C762T-16I/L fits industrial automation controllers where 50 I/O lines and 16-channel 10-bit ADC handle sensor matrix, keypad, and actuator drive in a single chip. Its 16 MHz clock and 121 ns instruction cycle provide responsive real-time control loops for PLC-style discrete I/O expansion. The -40C to +85C industrial grade supports factory-floor deployment without additional thermal hardening, while the 84-PLCC J-lead package eases socket-based prototyping and field replacement.
מומלץ
Motor Control Front-Ends
The PIC17C762T-16I/L is a strong fit for motor control front-ends that read Hall sensors, current shunts, and position encoders via the 16-channel 10-bit ADC, then drive H-bridge FETs through 50 GPIO pins. With 121 ns instruction cycle and 8x8 single-cycle hardware multiplier, it executes PI control loops with sub-microsecond latency. The wide ADC channel count also supports multi-axis simultaneous sensing in robotics and CNC machines.
מומלץ
Consumer Electronics with Analog Sensing
The PIC17C762T-16I/L serves consumer appliances (washing machines, microwaves, HVAC controls) where 16 ADC inputs read temperature, humidity, and level sensors while 50 GPIO drive displays, keypads, and relays. Its 16KB OTP program memory accommodates full feature sets with menu logic, fault diagnostics, and user-interface state machines. The 4.5V-5.5V single-rail operation simplifies power supply design in cost-sensitive consumer products.
מומלץ
Embedded Data Acquisition Systems
The PIC17C762T-16I/L fits 16-channel data loggers and embedded data acquisition front-ends because its 10-bit ADC multiplexes 16 analog inputs sequentially under firmware control. With 678 bytes RAM and 16KB EPROM, the device buffers sample blocks and stores calibration tables locally. The 16 MHz clock enables ~50 ksps aggregate throughput across multiple channels, suitable for slow industrial telemetry and instrumentation logging.
מומלץ
Instrumentation and Test Equipment
The PIC17C762T-16I/L supports bench-top instrumentation and test equipment where 16 ADC inputs digitize multi-range analog signals and 50 GPIO drive LCD segments, LED bargraphs, and keypad matrices. Its deterministic 121 ns instruction cycle and RISC architecture produce repeatable measurement timing critical for test gear calibration cycles. The 84-PLCC package is socket-friendly, allowing rapid chip swaps during validation testing.
מומלץ
HVAC and Building Control
The PIC17C762T-16I/L targets HVAC and building control systems where the 16-channel 10-bit ADC reads zone temperatures, duct pressures, and humidity transducers while GPIO drives damper motors, fan relays, and display panels. The industrial -40C to +85C grade handles unconditioned mechanical rooms and rooftop unit enclosures. Combined with the EPROM OTP memory model, it locks firmware at production preventing field tampering with safety-critical control logic.

הערות תכנון
Estimated: PIC17C762T-16I/L active current at 16 MHz with all peripherals on is approximately 25 mA at 5V, yielding 125 mW core dissipation. Add ADC reference current (typically 1-2 mA) and I/O sink/source load current separately. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of each VDD pin, plus a bulk 10 uF tantalum near the chip. The PLCC84 package has multiple VDD/VSS pins (typical 4-5 pairs); all must be connected for stable operation.
Estimated: thermal resistance theta_JA for 84-PLCC on a standard 4-layer PCB is approximately 35 C/W. At 125 mW active power and 25C ambient, junction rises only 4.4 C, leaving headroom to +85C industrial limit. However, if I/O pins source/sink significant current (20 mA per pin x 16 pins = 640 mA load), power dissipation rises to >3 W and a copper heatsink pour on PLCC underside becomes essential.
Use a 4-layer PCB with dedicated ground and power planes for the PIC17C762T-16I/L. Route the crystal/oscillator traces within 10 mm of OSC1/OSC2 with grounded guard ring on both sides to prevent clock noise injection. Place analog input traces away from digital switching lines; the 84-PLCC package has PORTB and PORTA as analog-capable pins so isolate those on inner PCB layers if possible. Provide a programming header footprint for in-circuit serial programming (ICSP) via RB6/RB7.
Do not operate PIC17C762T-16I/L below 4.5V or above 5.5V - the EPROM read margin and ADC reference become unreliable outside this range. Configuration word bits must be programmed correctly; an incorrect oscillator select can cause the device to fail to start with no clear symptom. The 16-level hardware stack has no overflow flag; deeply nested interrupts can corrupt return addresses - keep interrupt handlers minimal and avoid recursion. EPROM parts cannot be electrically erased; verify code in windowed PIC17C762JW prototypes before committing to OTP production.
