PIC16C76T-10I/SO Übersicht
What is an OTP microcontroller? An OTP (One-Time-Programmable) microcontroller uses EPROM-based program memory that can be written exactly once using a programming device; it cannot be erased or rewritten in-circuit. OTP sits in the hierarchy: microcontroller -> embedded MCU -> 8-bit MCU -> PIC16C mid-range family -> CMOS RISC core. OTP MCUs are favored for cost-sensitive volume production where code stability is final, in contrast to flash-based MCUs (PIC16F) which support in-circuit reprogramming.
Key features of the PIC16C76T-10I/SO include 35 single-word instructions (most single-cycle, branches 2-cycle), a programmable code protection bit, power-saving SLEEP mode, a 4-channel capture/compare/PWM module, a synchronous/asynchronous serial port (SSP/2) for SPI/I2C, an 8-bit parallel slave port, and dual analog comparators. These peripherals are tightly integrated to support motor control, sensor interfacing, and simple communication bridges without external glue logic.
The PIC16C76T-10I/SO uses Microchip's classic mid-range PIC16 architecture, which pairs a Harvard bus with 14-bit instruction words and 8-bit data, accessed through orthogonal register maps. The architecture's deterministic instruction timing (200 ns at 10 MHz) makes it well-suited to hard real-time control loops where predictable interrupt latency matters. Internal oscillator options, selectable oscillator sources, and a wide voltage range add flexibility for varied analog and digital subsystem designs.
Typical applications include industrial control, instrumentation, sensor signal conditioning, motor drive signal generation (using the CCP/PWM module), and embedded communication bridges. The integrated 8-bit A/D converter removes the need for an external ADC in many low-resolution measurement applications. For new designs, Microchip recommends the flash-based PIC16F76 as a modern drop-in alternative.
When designing with this part, verify programmer compatibility: OTP devices require an EPROM-style programmer (e.g., PICSTART Plus, MPLAB PM3) capable of programming the 14 KB OTP array and applying the proper Vpp programming voltage.

Typische Anwendungen
PIC16C76T-10I/SO ist geeignet für 6 Anwendungs: Industrial Process Control, Motor Drive PWM Control, Sensor Signal Conditioning Hubs, Embedded Communication Bridges, Consumer Appliance Control Boards, Instrumentation Front Panels.
Industrial Process Control
The PIC16C76T-10I/SO suits industrial process controllers where stable, locked firmware is desired. Its 14 KB OTP program memory, 22 I/O lines, and integrated 5-channel 8-bit ADC let the MCU read sensors and drive actuators directly. The 200 ns deterministic instruction timing at 10 MHz supports tight control loops, and the industrial -40 C to +85 C rating handles factory-floor environments. Compared with flash parts, OTP memory prevents accidental code drift in fielded equipment.
Empfohlen
Motor Drive PWM Control
The PIC16C76T-10I/SO's integrated CCP/PWM module, plus Timer2 as time base, generates the PWM waveforms needed for DC motor speed control, valve actuation, and small brushless drives. The 10 MHz clock offers fine PWM granularity, while the 22 I/O lines handle direction logic, brake signals, and Hall-sensor inputs. Industrial temperature grade and 5 V operation make it rugged for enclosed motor enclosures and pump controllers.
Empfohlen
Sensor Signal Conditioning Hubs
With its integrated 8-bit 5-channel ADC, dual analog comparators, and 22 digital I/O, the PIC16C76T-10I/SO acts as a sensor-conditioning hub, digitizing analog inputs and outputting conditioned logic-level signals. The PIC16C7X core's deterministic 200 ns instruction time makes it well suited to repetitive sampling loops. Industrial temperature rating supports outdoor sensor enclosures and HVAC monitoring.
Empfohlen
Embedded Communication Bridges
The PIC16C76T-10I/SO integrates SSP for SPI/I2C plus a USART, allowing it to bridge incompatible industrial buses or act as a sensor-to-host protocol translator. The 22 I/O lines handle flow-control signals, while 368 bytes RAM buffer short protocol packets. OTP memory locks the bridge protocol, ensuring deterministic behavior in ruggedized field installations.
Empfohlen
Consumer Appliance Control Boards
High-volume consumer appliances often lock firmware once finalized to control BOM cost, where the PIC16C76T-10I/SO excels. The MCU drives keypads, displays, and relays directly with its 22 I/O pins, runs state-machine firmware in 14 KB OTP, and uses the integrated ADC for temperature or level sensing. The wide-body 28-SOIC supports standard SMT lines, and the OTP memory prevents end-user firmware tampering.
Empfohlen
Instrumentation Front Panels
Bench and field instruments use the PIC16C76T-10I/SO to drive LCDs, keypads, and rotary encoders, while the 8-bit ADC digitizes analog front-end signals. The 22 I/O pins accommodate matrix keypads and indicator LEDs without external I/O expanders, and OTP memory locks calibration constants once the instrument ships. Operating from 4.0-5.5 V aligns with standard 5 V analog rails.

Designhinweise
OTP parts can only be programmed once. Verify firmware thoroughly with a flash equivalent (PIC16F76) before committing to OTP production. A single bad write wastes the die. Use MPLAB X simulator and ICD debugging on the PIC16F76 to validate code, then migrate to the PIC16C76T-10I/SO for the locked-production BOM.
The PIC16C76T-10I/SO operates from 4.0 V to 5.5 V; adding a 100 nF decoupling capacitor close to VDD and a 10 uF bulk capacitor is mandatory. For analog accuracy, decouple AVdd (pin 7 separate analog rail on some layouts) and AVss independently. Brown-out and power-on reset behavior must be configured via configuration bits before programming.
Place the crystal or resonator close to OSC1/OSC2 pins (8 and 9), with short traces and a ground guard ring for EMI-sensitive designs. Keep high-speed switching signals away from the analog ADC inputs (RA0-RA5). For ICSP, dedicate RB6/PGC and RB7/PGD as a header to allow programming without removing the MCU from the board.
Compliance-Informationen
