PIC16LCE625T-04E/SS Visão geral
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and a set of on-chip peripherals such as timers, communication controllers, and analog interfaces. Within the broader semiconductor hierarchy, the PIC16LCE625 belongs to the 8-bit microcontroller family, which sits beneath 16-bit and 32-bit MCU classes and is widely used in cost-sensitive, deterministic control applications. OTP devices like the PIC16LCE625 occupy the low-cost, low-power end of the PIC16 lineup.
Key features of this part include a RISC instruction set of 35 single-cycle instructions (200ns per instruction at 4MHz, except program branches which are two-cycle), Brown-out Detect/Reset, Power-on Reset (POR), and a Watchdog Timer (WDT). The device operates across the commercial and industrial temperature ranges typical of the PIC16LC series, making it suitable for embedded control products that require ROM-equivalent code protection without the per-unit programming overhead of mask ROM.
The PIC16LCE625T-04E/SS uses an external clock input architecture, allowing the system designer to choose the oscillator topology (RC, crystal, ceramic resonator, or external clock) best suited to the application. The 'L' prefix indicates the low-voltage (LC) operating range, while the 'E' suffix designates the extended (industrial) temperature grade and 'T' indicates tape-and-reel packaging for high-volume assembly.
Typical applications include consumer appliance control, simple sensor interfaces, low-end remote controls, and other cost-sensitive embedded products where deterministic 8-bit processing and on-chip OTP storage are sufficient. Compared to flash-based PIC16F parts, OTP variants offer lower per-unit cost for high-volume production runs.
When designing with this device, note that OTP memory can be programmed only once, so firmware must be fully validated before committing to production. Designers transitioning from PIC16F or PIC16LF parts should verify register maps and pin assignments because the OTP PIC16LCE family is pin- and code-compatible with the corresponding 'F' parts.

Aplicações típicas
PIC16LCE625T-04E/SS é adequado para 6 aplicaçãos: Consumer Appliance Control, Remote Control and IR Transmitter, Simple Sensor Interface Module, Automotive Cabin Accessory Controller, Battery-Powered Wireless Sensor Node, Educational and Hobby Embedded Projects.
Consumer Appliance Control
The PIC16LCE625T-04E/SS is a strong fit for low-cost consumer appliances (rice cookers, washing-machine user interfaces, microwave keypads) where 8-bit deterministic control and sub-$1 BOM cost matter more than peripheral density. The 3.5KB OTP holds a full appliance state-machine including button debounce, LED multiplex, and relay-timing logic without external memory. Brown-out Detect/Reset and POR handle unreliable mains-derived 3.3V/5V rails safely across brown-out events common in appliance environments.
Recomendado
Remote Control and IR Transmitter
Handheld IR remote controls benefit from the PIC16LCE625T-04E/SS's low cost and 4MHz execution speed: the 35-instruction RISC core runs NEC/RC-5/SONY IR encoders entirely in software with CPU headroom for keyboard scan and battery-monitor tasks. The 13 Industrial extended-temperature grade operation makes the part suitable for outdoor or automotive cabin remotes. OTP memory prevents firmware reverse-engineering, an important IP-protection benefit for consumer OEMs.
Recomendado
Simple Sensor Interface Module
Industrial sensor-interface boards (temperature, humidity, contact-closure, or 4-20 mA loop converters) often use a PIC16LCE625T-04E/SS to read a comparator or digital sensor and drive a relay or LED stack. The PIC16LCE625's analog comparator module and 13 GPIO pins handle sensor conditioning and alarm logic without an external op-amp. The PIC16LCE625's extended-temperature (-40C to +85C) operation suits factory-floor and outdoor enclosures where commercial-grade parts would fail.
Recomendado
Automotive Cabin Accessory Controller
In non-safety automotive cabin accessories (interior lighting, seat-position memory, mirror control, generic HVAC trim), the PIC16LCE625T-04E/SS can replace legacy 8-bit designs when an industrial-grade PIC16 part is acceptable. The Brown-out Detect/Reset and Watchdog Timer provide the resilience needed for 12V lead-acid load-dump environments. Note: this part is NOT AEC-Q100 qualified; for safety-critical body electronics use a Q-graded PIC16F variant instead.
Recomendado
Battery-Powered Wireless Sensor Node
Low-duty-cycle wireless sensor endpoints (door/window contact sensors, leak detectors, simple BLE beacons driven by an external radio) can use the PIC16LCE625T-04E/SS as a low-cost always-on supervisory controller that wakes the radio on event. The PIC16LCE625's Watchdog Timer, Brown-out Detect, and 3.0-5.5V operation are suited to 2xAAA/CR2032 systems regulated to 3.3V. For more demanding applications, migrate to the flash-based PIC16LF1554/SS in the same SSOP-20 footprint.
Recomendado
Educational and Hobby Embedded Projects
The PIC16LCE625T-04E/SS is suitable for university embedded-systems courses and hobbyist projects teaching 8-bit MCU fundamentals: GPIO, timers, interrupts, and the PIC16 enhanced mid-range architecture. The 20-SSOP package is hand-solderable for prototypes, and the PIC16 instruction set's simplicity (only 35 instructions) makes assembly-language teaching tractable. For cost-effective teaching labs, students may also prototype on the PIC16F628-04/SS flash equivalent and migrate to PIC16LCE625 for high-volume final designs.

Notas de projeto
Because the PIC16LCE625T-04E/SS uses One-Time Programmable memory, firmware bugs discovered after programming are unrecoverable - the device must be discarded and re-programmed on a fresh unit. Always burn a few prototype units and run extended validation (over-voltage, brown-out, watchdog timeout, temperature cycling) before committing to volume programming. For new designs, prefer the flash-based PIC16F628-04/SS or PIC16F1827T-I/SS in the same SSOP-20 footprint to allow in-system firmware iteration.
The PIC16LCE625T-04E/SS supply rail must be decoupled with a 100 nF ceramic capacitor placed within 5 mm of the VDD pin and a bulk tantalum or electrolytic 10 uF capacitor on the same node. Per Microchip PIC16CE625 datasheet power-supply recommendations, slow VDD rise times (< 0.05 V/ms) can cause Power-on Reset failures; if the upstream regulator has a soft-start, add a 1 kohm pull-up to MCLR or use an external POR supervisor such as MCP100-300I/TO for mission-critical applications.
For the 20-SSOP package, follow the SSOP-20 land pattern with 0.65 mm pitch and 5.30 mm body width per JEDEC MO-150. Keep the oscillator traces (OSC1/OSC2, pins 1-2) as short as possible and guard them with a grounded copper pour to reduce EMI pickup - the PIC16LCE625T-04E/SS is sensitive to clock-injected noise because the internal core synchronizes to the external oscillator. The MCLR pin (pin 3) should have a 10 kohm pull-up to VDD and a 100 nF capacitor to ground for clean reset behavior.
The PIC16LCE625T-04E/SS in SSOP-20 has a thermal resistance around 100 C/W (theta-JA), so under industrial-temperature operation with continuous CPU activity at 4 MHz, the junction rise above ambient is typically <10 C. Estimated: at ambient 25 C and 4 MHz active mode drawing ~2 mA at 5V, total power is ~10 mW and self-heating is negligible. However, in sealed enclosures with no airflow, derate by 10 C for every 2 mA additional current draw from I/O loads.
