PIC16C715T-20E/SO - 8-bit OTP MCU, 3.5KB, 20MHz | Microchip
MPN: PIC16C715T-20E/SO ✗ Cuối đờiPIC16C715T-20E/SO Tóm tắt
An OTP-based 8-bit PIC microcontroller is a single-chip computing core that combines a RISC CPU, non-volatile program memory, RAM, peripherals, and I/O on one silicon die. Unlike flash-based MCUs, OTP memory can be programmed once after manufacture, lowering unit cost for high-volume production runs where firmware is stable. The PIC16C71X family sits within the broader PIC mid-range architecture, which itself is a member of the 8-bit microcontroller category under embedded microcontrollers and integrated circuits. The part also supports in-circuit serial programming (ICSP) for development despite its OTP nature.
Key features include 35 single-word instructions, an 8-bit timer/counter with a prescaler, a watchdog timer with on-chip RC oscillator, and 13 I/O pins with individual direction control. The integrated 8-bit A/D converter has 4 input channels and supports both ratiometric and absolute voltage measurements with reference options from device VDD or external VREF. Brown-out reset and power-on reset are integrated, reducing external component count.
The architecture is built on a Harvard-style RISC core with a 14-bit instruction word, two-stage pipeline, and 8-bit data path. The OTP program memory is implemented as EPROM cells, providing non-volatility at lower cost than flash. The 20 MHz clock rate delivers 5 MIPS of throughput, sufficient for sensor sampling, motor control loops, and simple user-interface tasks.
Typical applications include automotive body controllers, sensor signal conditioning, simple motor drivers, battery management, and white-goods appliance controls. The automotive temperature grade (-40C to +125C) qualifies the part for under-hood and cabin electronic modules. When designing with this part, ensure the ICSP programming header is accessible during board bring-up, because OTP memory cannot be erased and re-flashed in production.

Ứng dụng tiêu biểu
PIC16C715T-20E/SO phù hợp cho 6 Áp dụngs: Automotive Body Controllers, Industrial Sensor Signal Conditioning, Battery-Powered White Goods Appliances, Simple DC Motor Speed Control, LED Lighting Controllers, Battery Management Monitoring.
Automotive Body Controllers
The PIC16C715T-20E/SO fits automotive body controller modules because its automotive -40C to +125C temperature grade meets cabin and under-hood thermal stress while its 3.5KB OTP memory holds fixed-function body-control firmware. The 8-bit 4-channel ADC handles analog sensor inputs such as switch contact voltages, thermistor dividers, and battery current shunts. The integrated watchdog timer and brown-out reset ensure recovery from automotive load-dump transients without external supervisory ICs.

Industrial Sensor Signal Conditioning
The PIC16C715T-20E/SO is well suited to industrial sensor signal conditioning because its 8-bit 4-channel ADC supports ratiometric measurements using the supply as reference, and the 20 MHz core delivers 5 MIPS for linearization math and digital filtering. The 13 I/O pins drive LEDs, optocouplers, and relay coils directly. Extended temperature operation allows deployment in factory-floor cabinets without additional thermal conditioning.

Battery-Powered White Goods Appliances
In white-goods appliances such as dishwashers, washing machines, and microwave ovens, the PIC16C715T-20E/SO provides a cost-optimized 8-bit controller for user-interface scanning, timer sequencing, and motor-load switching. The 13 I/O pins multiplex keypad matrices, seven-segment displays, and TRIAC drivers. OTP memory locks the final firmware to prevent field tampering, an advantage over flash parts in cost-sensitive high-volume appliances.
Được đề xuất
Simple DC Motor Speed Control
The PIC16C715T-20E/SO can implement a basic PWM-based DC motor speed controller by toggling an I/O pin in software and reading back-EMF through the ADC for closed-loop regulation. The 8-bit timer provides the timebase for PWM generation, and 13 I/O pins allow direction control, brake logic, and fault feedback. Operating at 5 MIPS, the controller can run a 5 kHz PWM with 1 percent duty-cycle resolution and still service the ADC interrupt.
Được đề xuất
LED Lighting Controllers
The PIC16C715T-20E/SO can drive LED lighting fixtures through PWM dimming on its 13 I/O pins while sampling ambient light or button inputs through the 8-bit ADC. The 5 MIPS throughput is sufficient for color-mixing algorithms in RGB fixtures or for blinking-pattern generation in signage. OTP memory locks dimming curves to prevent field tampering and ensures deterministic boot behavior in safety-critical signage.
Được đề xuất
Battery Management Monitoring
The PIC16C715T-20E/SO is well matched to battery monitoring peripherals where it samples cell voltage and current via the 8-bit ADC, drives status LEDs through GPIO, and asserts low-battery cutoffs through firmware logic. The automotive temperature grade allows deployment in engine-bay battery packs, and the watchdog timer protects against firmware lock-up during long standby periods. OTP memory eliminates field-reprogramming concerns in safety-certified packs.

Ghi chú thiết kế
The PIC16C715T-20E/SO requires a stable 4.5V to 5.5V supply with bulk decoupling of 10 uF tantalum or electrolytic plus a 0.1 uF ceramic cap placed within 5 mm of the VDD pin. Brown-out reset (BOR) is integrated but should be enabled in the configuration word to protect against voltage sags below 4.5 V. A series ferrite bead or 10 ohm resistor on VDD reduces switching-injected noise from relays or motor loads sharing the rail.
Layout the ICSP header (PGC on RB6, PGD on RB7, MCLR/VPP on RA5, VDD, VSS) on every board, even production units. Because OTP memory cannot be erased, a fresh blank part must be installed if firmware changes are required. Keep the ICSP traces short (under 50 mm) and add 4.7 kohm pull-ups on PGC and PGD to prevent in-circuit programming glitches from stray capacitance.
Common pitfalls: (1) Leaving the MCLR pin floating - it must be tied to VDD through a 10 kohm resistor or driven by an external supervisor; a floating MCLR causes intermittent resets. (2) Using the internal RC oscillator without calibration - the 4 MHz internal RC drifts up to 8 percent over temperature; for UART timing-sensitive applications use an external crystal. (3) Assuming the watchdog timer is enabled by default - it is OFF after POR and must be enabled in firmware.
