PIC16LC710T-04E/SS Overview
What is a microcontroller? A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (here OTP EPROM), working RAM, and peripheral blocks such as timers, communication ports, and ADCs. Within the broader taxonomy, the PIC16LC710 sits under 8-bit MCU -> mid-range MCU -> PIC16 family -> CMOS OTP microcontroller. Its on-chip ADC, low-power CMOS design, and Harvard RISC architecture made it a workhorse for embedded control in the late 1990s and remain reference designs for cost-sensitive analog monitoring today.
Key features of the PIC16LC710T-04E/SS include four 8-bit A/D converter channels with 8-bit resolution, two 8-bit timers plus one 16-bit timer with prescaler and external crystal/clock increments during sleep, a 13-bit instruction word, a watchdog timer, and power-on reset. The 20-SSOP package (5.30 mm body width, 0.65 mm pitch) is footprint-compatible with the rest of the PIC16C71x family and is supplied on tape-and-reel for high-volume surface-mount assembly.
The PIC16LC710T-04E/SS is pin-to-pin compatible with the PIC16LC711 and PIC16C71x OTP/EPROM siblings, allowing designers to migrate code across speed grades, memory densities, and temperature grades. Although the EPROM-based "LC" variant has been superseded in new designs by flash-based PIC16F1xxx devices, it remains in active distribution for industrial automation, consumer electronics, and automotive aftermarket applications where extended-temperature silicon is mandatory and code is finalized.
Typical applications include battery chargers, sensor signal conditioning, HVAC control, automotive body electronics, and industrial automation. For new designs, the pin-compatible PIC16F690 family offers flash memory, more peripherals, and lower cost. The "E" temperature grade allows deployment in under-hood automotive, outdoor industrial, and white-goods environments.
When designing with this part, ensure the supply rail stays within 2.5 V-6.0 V and the oscillator configuration matches the chosen speed grade. The MCLR/VPP pin must be correctly biased for normal operation versus in-system programming. For new designs prefer PIC16F1xxx flash parts unless EPROM stability is required.

Typical Applications
PIC16LC710T-04E/SS is suitable for 6 applications: Industrial Sensor Signal Conditioning, Automotive Body Electronics, Battery Charger Control, HVAC and White-Goods Control, Consumer Electronics User Interface, Security and Alarm System Peripherals.
Industrial Sensor Signal Conditioning
The PIC16LC710T-04E/SS is well suited to industrial sensor signal conditioning where its 4-channel 8-bit ADC digitizes analog inputs from thermocouples, strain gauges, and pressure transducers. The extended -40 °C to +125 °C temperature window allows deployment in factory-floor cabinets and outdoor enclosures without additional thermal management. Placed between the sensor bridge and an RS-485 transceiver, the MCU performs cold-junction compensation, linearization, and digital filtering. At 4 MIPS it has just enough headroom for 100 Hz sampling on all four channels. Unlike higher-resolution ADCs, the 8-bit converter is adequate for threshold detection and on/off control, where its low cost and integrated timers offset the resolution limit.
Recommended
Automotive Body Electronics
The PIC16LC710T-04E/SS is qualified for automotive aftermarket and body-electronics modules that require extended-temperature silicon but not full AEC-Q100 qualification. Its ADC monitors battery voltage, interior temperature, and switch contact closures, while its PWM peripherals drive LED dimmers and small solenoids for door locks or mirror adjustment. The 2.5 V to 6.0 V supply range aligns with 12 V automotive rails after a simple LDO drop. Placed on a daughter card behind a main CAN transceiver, the MCU handles local I/O expansion. Its 200 ns instruction cycle and 36 bytes of RAM are sufficient for state-machine control, though not for the J1939 protocol stack itself.
Recommended
Battery Charger Control
The PIC16LC710T-04E/SS forms the control brain of low-to-mid-power battery chargers for lead-acid, NiMH, and small Li-ion packs. Its ADC reads battery voltage and charge current while its PWM peripheral regulates a buck or flyback converter's duty cycle. The 4 MHz clock is fast enough to support switching frequencies up to 100 kHz with adequate control-loop resolution. Placed between the current-sense amplifier and the MOSFET gate driver, the MCU implements constant-current/constant-voltage (CC/CV) profiles, temperature fold-back, and charge-termination algorithms. Compared with pure analog charge controllers, the PIC16LC710T-04E/SS enables firmware-upgradeable charging profiles and adaptive end-of-charge detection without hardware changes.
Recommended
HVAC and White-Goods Control
The PIC16LC710T-04E/SS fits HVAC control boards and white-goods appliances where its extended-temperature silicon survives under-cabinet and outdoor-unit environments. Its timers drive triac phase-angle control for fan-speed regulation and heater switching, while its ADC reads thermistor inputs from evaporator and ambient sensors. The 20-SSOP package is small enough for compact board layouts inside refrigerator or air-conditioner control panels. At 4 MIPS the MCU implements defrost cycles, compressor anti-short-cycling timers, and user-interface handling without external logic. The OTP EPROM silicon ensures code stability over a 10+ year product lifetime, an advantage over flash parts that may lose charge in high-temperature operation.
Recommended
Consumer Electronics User Interface
The PIC16LC710T-04E/SS serves as a low-cost user-interface controller in consumer electronics such as coffee machines, microwave ovens, and countertop appliances. Its 13 I/O pins drive 7-segment LED displays, keypads, and indicator LEDs directly without external logic. The PWM peripheral produces variable-intensity backlight control, while the 8-bit ADC reads potentiometer inputs for analog knob feedback. Placed between the human-interface panel and the main power-control MCU, the device offloads scan-and-debounce duties. Its small 20-SSOP footprint and 36 bytes RAM are sufficient for state-machine UI code; designers prefer the OTP variant when code is finalized and long-term supply stability matters more than in-field reprogrammability.
Recommended
Security and Alarm System Peripherals
The PIC16LC710T-04E/SS fits distributed sensor nodes in security and alarm systems where its ADC monitors PIR motion detectors, glass-break sensors, and door-reed switches. The extended temperature grade ensures operation in unheated garages, warehouses, and outdoor enclosures. Its sleep mode with timer-driven wake-up enables multi-year battery life on a single cell pair. Placed on a small remote board and connected to a central panel via a wired or low-power RF link, the MCU handles local event debouncing and tamper detection. Compared with purely analog sensor interfaces, the programmable MCU enables per-channel sensitivity calibration stored in EPROM, improving false-alarm rejection across installations.

Key Differentiators
- Extended -40 C to +125 C temperature grade (vs PIC16LC710T-04I/SS)
- OTP EPROM code stability for 10+ year product life (vs PIC16F690-I/SS)
- Tape & Reel packaging for high-volume SMT (vs PIC16LC710-04/SS)
Design Notes
Place a 100 nF ceramic decoupling capacitor as close as possible to the VDD pin (pin 20) and a bulk 10 uF tantalum or aluminum cap on the supply rail. The PIC16LC710T-04E/SS draws roughly 2 mA at 4 MHz and 5 V. Adding a 100 ohm series resistor plus 10 uF bulk at the regulator output reduces switching-noise injection. Brown-out reset is enabled by default in the CONFIG word; verify the BOR voltage matches your supply tolerance to avoid spurious resets during cranking or motor inrush.
Route the oscillator traces (OSC1/OSC2) as short as possible and keep them away from analog inputs to minimize coupling. Use a guarded ground plane around the ADC pins (RA0-RA5) and provide a single-point ground return for the analog reference. The 20-SSOP pin pitch is 0.65 mm, so the land pattern should follow the IPC-7351 SSOP-20 nominal with 0.40 mm pads. Route ADC traces in a star from the VREF capacitor to avoid digital-return currents corrupting the conversion.
Do not float the MCLR/VPP pin - tie it to VDD through a 10 kohm resistor or directly when not using in-system programming. The ADC requires an acquisition time of at least 19.2 us at 4 MHz; reading the ADC too quickly produces non-linear results. When migrating from PIC16F690 firmware, note that flash write/erase routines replace EPROM programming and the configuration bits differ - verify the CONFIG word before programming. For OTP variants, double-check code in a flash equivalent (PIC16C71x emulator or PIC16F690 with adjusted header) before committing to the one-time-programmed device.
Compliance Information
RoHS and lead-free status depend on date code; verify with vendor CoC. Not AEC-Q100 qualified, but E-grade silicon supports extended automotive-aftermarket operation.
