PIC16C773T-E/SS 概要
A microcontroller (MCU) is a single-chip computer containing a CPU, program memory, data RAM, and configurable peripherals. The PIC16C family is the mid-range tier of Microchip's PIC architecture, positioned between the baseline PIC10/14 families and the high-pin-count PIC17/18 families, offering 35 single-word instructions and source-level compatibility with PIC16C5X and PIC12CXXX devices for easy migration. OTP (One-Time-Programmable) memory allows the user to program the device once during production with a custom firmware image, making it well suited to cost-sensitive high-volume embedded products where firmware changes are not required after deployment.
Key features of the PIC16C773 include 200ns instruction execution at 20MHz, a hardware USART for asynchronous serial communication, a Master Synchronous Serial Port (MSSP) supporting both SPI and I2C master/slave modes, and a 12-bit successive-approximation ADC with up to 6 analog input channels sampled from device pins. The integrated peripherals are accessed through 22 general-purpose I/O pins, with programmable weak pull-ups and interrupt-on-change capability on selected ports for direct switch and keypad interfacing without external glue logic.
Architecturally, the PIC16C773 uses a Harvard RISC core with separate program and data buses, a hardware multiplier, and a 14-bit instruction word that improves code density relative to 8-bit CISC architectures. The 12-bit ADC shares the analog input pins with port A and is suitable for sensor signal acquisition in industrial control loops, while the USART/MSSP combination enables communication with both legacy RS-232/RS-485 modems and modern I2C sensor buses. The 28-SSOP package provides moderate board footprint reduction versus the 28-pin PDIP, making the part attractive for space-constrained designs.
Typical applications include industrial automation controllers, automotive body and chassis subsystems, sensor-interface modules, low-cost consumer electronics, HVAC controllers, and small appliance control boards. The 4-5.5V operating range, automotive -40C to +125C temperature grade (designated by the E suffix), and 12-bit ADC make it appropriate for harsh-environment analog measurement tasks. The OTP memory architecture suits designs with locked firmware images where the lower per-unit cost of OTP outweighs the field-reprogrammability of Flash-based PIC16F variants.
A key design consideration for the PIC16C773T-E/SS is that OTP memory cannot be erased or rewritten, so the firmware must be fully validated before production programming. Engineers migrating from Flash-based PIC16F equivalents must use the same development toolchain (MPLAB X IDE, MPASM assembler, or C18 compiler) but plan for one-time-programming flow.
This page synthesizes distributor pricing, drop-in same-package alternatives (including automotive-grade and Flash equivalents in the PIC16C family), and practical design notes that complement - but do not duplicate - the manufacturer datasheet.

Industrial Automation Controllers
The PIC16C773T-E/SS is well suited to industrial automation controller boards where the 12-bit 6-channel ADC acquires 4-20mA loop signals through external shunt resistors and the USART drives RS-485 transceivers for Modbus RTU communication. Its -40C to +125C extended temperature range and OTP-only memory lock the firmware image, preventing accidental field re-flashing that could compromise certified industrial equipment. The 22 digital I/O pins handle discrete sensor inputs and relay-driver outputs directly, while the MSSP provides SPI or I2C connectivity to EEPROM data logs and digital temperature sensors on the same board.

主な差別化要因
- Automotive-extended temperature OTP MCU in 28-SSOP （vs PIC16C773-I/SS)
- 12-bit ADC at 20 MHz instruction rate （vs PIC16F873A-I/SS)
- OTP memory locks firmware against modification （vs PIC16F876A-I/SS)
設計ノート
Place a 100nF ceramic decoupling capacitor within 1cm of each VDD pin (pins 18 and 28) with a short ground return to the nearest VSS pin. Add a 10uF bulk tantalum or aluminum-polymer capacitor at the regulator output to supply transient current during ADC conversions and USART transmissions. Avoid routing high-current switching traces near the VDD pins to minimize digital switching noise coupling into the analog supply rail and degrading 12-bit ADC linearity.
OTP memory is one-time-programmable and CANNOT be erased or rewritten. If your firmware requires field updates or iterative development cycles, migrate to a Flash-based PIC16F876A-I/SS in the same 28-SSOP package. The configuration word (address 2007h) must be programmed with the correct oscillator mode, watchdog timer setting, and code-protect bits before any program memory is written; incorrect configuration words can brick the device since OTP cannot be re-programmed.
The 28-SSOP package has a 0.65mm pitch and a thermal pad area on the underside; provide 0.4mm-wide PCB traces between pins and a continuous ground plane on the layer beneath the IC. For high-noise environments, add a guard ring connected to analog ground around the ADC input pins (RA0-RA5) to improve ADC signal integrity. Keep crystal traces (OSC1/OSC2) short and surrounded by ground pour to reduce EMI and improve oscillator stability across the -40 C to +125 C temperature range.
