PIC16C711T-04E/SS - 4MHz 8-Bit OTP MCU 1.75KB | Microchip SSOP-20
MPN: PIC16C711T-04E/SS ✗ Akhir HidupPIC16C711T-04E/SS Ringkasan
An 8-bit microcontroller (MCU) is a small, low-power computer-on-a-chip that integrates a CPU core, program memory (ROM/Flash/OTP), data RAM, and peripherals onto a single silicon die. It executes instructions fetched from non-volatile program memory and operates on data stored in volatile RAM. Microcontrollers sit in the device hierarchy deep-IC > microcontroller > embedded controller > semiconductor. The "PIC" family from Microchip uses a Harvard architecture and a reduced instruction set (RISC) optimized for deterministic, single-cycle execution. OTP (One-Time Programmable) versions like the PIC16C711 are programmed once with a device programmer and cannot be electrically erased, distinguishing them from Flash-based siblings such as the PIC16F716, which Microchip explicitly recommends as the modern equivalent.
Key features include 4 channels of 8-bit Analog-to-Digital conversion (ADC), a Brown-out Reset (BOR), Power-on Reset (POR), and a Watchdog Timer (WDT). The core runs each instruction in 200 ns at 4 MHz, executes only 35 single-word instructions, and offers 13 I/O pins plus an 8-bit timer. Operating voltage is 4.0V to 6.0V and the part operates over the standard PIC16C commercial/extended temperature grade.
The PIC16C711 architecture places the ADC and core analog reference on-chip, eliminating external analog conditioning for low-channel-count embedded designs. Its 14-bit instruction word (vs. 12-bit on PIC16C5X baseline parts) gives a flatter mid-range instruction set, and the chip is source-code compatible upward through the PIC16CXX mid-range family. The "/SS" suffix denotes the SSOP-20 package, the "T" denotes Tape & Reel, "04" denotes 4 MHz maximum clock, and "E" denotes the Extended operating temperature range.
Typical applications include appliance control, sensor signal conditioning with on-chip ADC, low-cost remote keyless entry transmitters, smoke-detector front-ends, battery chargers, and small motor driver logic boards where the ADC is the primary analog asset and BOM cost is critical.
Designers should bias the MCLR pin properly and follow Microchip's recommended decoupling (100 nF + 10 uF bulk) when laying out the PCB. Use ICD or a production programmer compatible with OTP windows to program the device.

Aplikasi Umum
PIC16C711T-04E/SS cocok untuk 6 aplikasis: Appliance Control Boards, Smoke Detector Front-End, Remote Keyless Entry Transmitter, Battery Charger Control, Sensor Signal Conditioning, Small Motor Driver Logic Board.
Appliance Control Boards
The PIC16C711T-04E/SS is well suited to appliance control boards where a small BOM and an on-chip 4-channel 8-bit ADC keep cost low. Its 4 MHz core executes 200 ns instruction cycles, which is ample for relay sequencing, button debouncing, and sensor readout in washing-machine, dishwasher, and microwave front panels. Brown-out Reset and Power-on Reset protect against brown-out and supply-glitch misbehavior on noisy AC-derived rails. The 13 I/O pins drive LED indicators, keypad matrices, and triac interface optos. With 1.75KB OTP and 68 B RAM, the part fits typical 8-bit appliance state machines comfortably.

Smoke Detector Front-End
The PIC16C711T-04E/SS works well in ionization-chamber smoke detector front-ends where its on-chip 8-bit ADC digitizes the chamber reference voltage directly. The 4-input ADC samples the photo-detector or ionization chamber bias through an external divider, and the 4 MHz core handles periodic chamber self-test routines and alarm-tone chirp scheduling. Brown-out Reset is critical for battery-powered detectors because it forces a known state when a weakening 9V battery sags. The 13 I/O drive a piezo alarm transducer, status LED, and interconnect line. The Extended (E) temperature grade suits the elevated thermal environment inside detector housings.

Remote Keyless Entry Transmitter
The PIC16C711T-04E/SS suits single-button or multi-button key-fob transmitters where ultra-low standby current, deterministic timing, and small package size matter. At 4 MHz it can drive a SAW resonator-based RF oscillator stage via one of its 13 I/O pins, encoding a rolling-code bitstream. The 1.75KB OTP holds the encoder firmware and a serial number, while 68 B of RAM is sufficient for stack and keypress scratch state. Brown-out Reset protects against weak coin-cell voltage. The SSOP-20 footprint keeps the fob PCB compact, and the OTP program memory prevents code reverse-engineering by competitors.

Battery Charger Control
The PIC16C711T-04E/SS is appropriate for low-rate NiCd / NiMH charger controllers where the 4-channel 8-bit ADC monitors pack voltage, pack temperature (via thermistor), charge current shunt, and timer. The Brown-out Reset prevents recharge attempts when the wall adapter sags, and the Watchdog Timer recovers the charger from software faults. The 4 MHz core and 1.75KB OTP hold a state machine that implements -delta-V termination, dT/dt temperature cutoff, and timed top-off. The Extended temperature grade handles the warmth of enclosed charging bays, and the SSOP-20 footprint drops onto compact wall-worm charger boards.

Sensor Signal Conditioning
The PIC16C711T-04E/SS handles sensor signal conditioning nodes that need an on-chip ADC and a small microcontroller for linearization and threshold decisions. The 4 ADC inputs read thermistor bridges, photocells, and strain gauges directly, while the 4 MHz core runs linearization math and toggles output relays. Brown-out Reset handles unstable sensor-supply rails. With 1.75KB OTP for calibration constants and 68 B RAM for moving averages, the part fits HVAC duct sensors, weighing-scale load-cell digitizers, and industrial process indicators. The 13 I/O drive displays, optos, and serial bridges.

Small Motor Driver Logic Board
The PIC16C711T-04E/SS fits small brushed-DC and unipolar stepper motor driver logic boards where 13 pins can be allocated to direction, enable, fault-feedback, and limit-switch inputs. The 4 MHz core sequences the commutation state machine for 1- or 2-axis motion control, and the 4-channel ADC reads back current-sense amplifier outputs for stall detection. Brown-out Reset avoids undefined driver outputs during supply dips. The 1.75KB OTP holds lookup tables for acceleration ramps, and 68 B RAM tracks position counters. The Extended temperature grade tolerates proximity to motor heat sinks.

Diferensiator Kunci
- Extended (E) operating temperature grade in SSOP-20 (vsPIC16C711-04/SS)
- Tape & Reel (T) packaging for high-volume assembly (vsPIC16C711-04E/SS)
- Modern flash-based replacement pin compatibility (vsPIC16F716)
Catatan Desain
The PIC16C711T-04E/SS operates from 4.0 V to 6.0 V; add a 100 nF ceramic decoupling capacitor close to VDD (pin 14) plus a 10 uF bulk capacitor on the board supply. Brown-out Reset activates when VDD drops below the BOR threshold, so design the supply with a hold-up capacitor large enough to ride through relay or triac-commutation glitches typical of appliance and motor-control boards.
For the 20-pin SSOP package, route the oscillator traces (OSC1, OSC2) short and guarded by a ground pour to minimize EMI pickup. Place the decoupling capacitor within 5 mm of the VDD pin and keep the MCLR pull-up within 10 mm of pin 4. Use a 4-layer stack-up with a dedicated ground plane for noise-sensitive analog ADC readings on RA0-RA3.
Do not assume OTP-programmed parts can be re-blanked: the PIC16C711T-04E/SS is One-Time Programmable and a programming error burns the program memory permanently. Always program a known-good image first, and consider the PIC16F716 (Flash) for prototypes that require iteration. Also note that the E (Extended) grade part is not a drop-in for industrial (-40C to +85C) needs at extremes - verify your temperature profile against the datasheet.
Keep analog inputs RA0-RA3 away from digital switching traces (RB port, oscillator) to preserve ADC accuracy. The 8-bit ADC has a typical 1-LSB noise floor; route the AVSS path back to a single-point ground tied to VSS at the MCU to avoid ground-loop offset. Reference voltages on RA3 should be bypassed with a 100 nF capacitor to minimize ADC noise on lower-voltage measurements.
