PIC16CE625T-04I/SS 개요
An 8-bit microcontroller (MCU) is a single-chip computer with an 8-bit data bus, integrating a CPU, memory, and peripherals. The PIC16CE62X family belongs to Microchip's PICmicro mid-range architecture, which sits hierarchically within the broader categories: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. These devices use a Harvard RISC architecture that executes one instruction per clock cycle (except branches), making them highly deterministic and efficient for low-power embedded control. The 'CE' suffix indicates the family integrates on-chip EEPROM data memory alongside OTP program memory, distinguishing it from 'C' OTP-only and 'F' Flash variants.
Key features include 35 instructions, 14-bit instruction word, 8-level hardware stack, 4 oscillator modes (RC, XT, HS, LP), 2 analog comparators with programmable reference, 8-bit timer/counter with 8-bit prescaler, one 16-bit timer/counter, 2 capture/compare/PWM modules, in-circuit serial programming (ICSP), and an internal brown-out reset circuit. Power consumption is typically <2 mA active at 4 MHz/5V and <1 uA standby, which suits battery-backed and always-on designs.
The PIC16CE625 architecture combines a 14-bit RISC CPU with dual-bus Harvard memory, allowing simultaneous instruction fetch and data access. The integrated on-chip EEPROM (128 bytes) provides non-volatile user data storage distinct from program memory, useful for storing calibration values, configuration parameters, or runtime counters that survive power cycles. The OTP program memory (3.5KB) supports low-cost production programming, while the peripheral set (comparators, CCP, timers, USART) addresses typical embedded control tasks.
Typical applications include remote controls, sensor interfaces, low-cost consumer appliances, security alarm panels, automotive body electronics, and industrial control boards. Its EEPROM-backed data retention makes it a fit for designs needing non-volatile user parameter storage. When designing with this device, ensure decoupling capacitors (100 nF + 10 uF) are placed within 5 mm of VDD, and that the MCLR pin is pulled up through 10 kohm with optional 100 nF noise suppression.

일반적인 애플리케이션
PIC16CE625T-04I/SS 적합 용도: 7 애플리케이션s: Remote Control Transmitters, Industrial Sensor Interfaces, Consumer Appliance Control, Security Alarm Panels, Automotive Body Electronics, Hobby and Educational Projects, Battery Charger Controllers.
Remote Control Transmitters
The PIC16CE625T-04I/SS suits handheld remote controls because its 3.5KB OTP program memory accommodates typical RC5/RC6 or NEC protocol decoders, while 128 bytes EEPROM stores paired device addresses and rolling-code counters that survive battery swaps. Operating at 4 MHz under 3.0-5.5V from two AAA cells, the MCU draws under 2 mA active and sub-uA in sleep, supporting years of battery life. The 13 I/O pins easily drive IR LEDs and read matrix keypads. Place a 100 nF decoupling capacitor within 5 mm of VDD, and bias MCLR with a 10 kohm pull-up for production stability.
추천
Industrial Sensor Interfaces
The PIC16CE625T-04I/SS is a strong fit for industrial sensor signal conditioning and data acquisition front ends because its two integrated analog comparators directly digitize thermistor, photodiode, or Hall-effect signals without external op-amps. The 128-byte EEPROM retains calibration coefficients across power cycles, enabling per-unit trimming. With 4 MHz operation over -40C to +85C, it handles factory-floor environments. The 13 I/O pins multiplex multiple sensors, and the 8-level hardware stack supports structured C-style control flow.
추천
Consumer Appliance Control
The PIC16CE625T-04I/SS powers low-cost consumer appliances such as coffee makers, washing machines, and microwave oven control boards. Its 3.5KB OTP program memory handles user-interface state machines, timing routines, and safety interlocks, while EEPROM stores user preferences (brew strength, child lock) that survive power cycles. The two analog comparators monitor temperature and water level, while PWM output drives motor control signals. Industrial -40C to +85C operation ensures kitchen-environment reliability. Combined with low unit cost, this part is well-suited to appliance OEMs.
추천
Security Alarm Panels
The PIC16CE625T-04I/SS provides a cost-effective controller for residential and small-commercial alarm panels, where its 128-byte EEPROM stores zone configuration and event logs that survive power loss. The watchdog timer and brown-out reset ensure reliable operation during brown-outs and EMI events typical of alarm installations. 13 I/O pins interface PIR sensors, door contacts, sirens, and keypad matrices. The integrated comparators monitor backup battery voltage for low-battery alerts. Operating at 3.0-5.5V with low standby current suits battery-backed alarm architectures.
추천
Automotive Body Electronics
The PIC16CE625T-04I/SS fits automotive body-electronics modules such as window lift controllers, seat position memories, and lighting timers, where its 128-byte EEPROM retains trim settings (seat position, mirror angle) across power cycles. The two comparators monitor current sensing for stall detection on window motors, while PWM controls motor speed via H-bridge drivers. The 20-SSOP package's small footprint enables placement inside door modules. Note that NRND status makes long-term automotive programs challenging; the PIC16CE625T-04E/SS variant extends the operating range to 125C for under-hood-adjacent use.
추천
Hobby and Educational Projects
The PIC16CE625T-04I/SS remains popular for hobbyists, students, and educational labs due to Microchip's extensive PIC16 architecture documentation, MPLAB X IDE support, and low-cost development tools like the PICkit 3. The 3.5KB OTP, 128 bytes RAM, and 13 I/O pins provide ample resources for introductory embedded projects (LED chasers, line-following robots, basic sensor boards). Its mid-range 14-bit instruction set is widely taught in universities. Compatibility with PIC16F628A simplifies migration to Flash once students progress beyond OTP limitations.
추천
Battery Charger Controllers
The PIC16CE625T-04I/SS can implement CC/CV (constant-current/constant-voltage) charger algorithms for lead-acid, NiMH, or Li-ion battery packs, using its analog comparators to monitor battery voltage and charge current. The 128-byte EEPROM stores battery chemistry parameters and charge profiles, while the PWM module drives MOSFET switches via gate drivers. With sub-uA sleep current, the MCU maintains monitoring functions on a low drain when charging is complete. The industrial -40C to +85C range accommodates garage and outdoor charging stations.

설계 노트
Place a 100 nF ceramic decoupling capacitor within 5 mm of the VDD pin (pin 20) and a bulk 10 uF tantalum or ceramic capacitor near the VDD/VSS pair to suppress switching transients. The PIC16CE625T-04I/SS draws less than 2 mA at 4 MHz active and under 1 uA in sleep mode, so a coin-cell backup can sustain sleep-mode parameter retention for years. Avoid routing high-current switching traces near VDD/VSS to prevent supply-induced resets.
Keep the MCLR/VPP pin (pin 4) routed with a short trace to a 10 kohm pull-up resistor to VDD, and optionally a 100 nF capacitor for noise immunity. For in-circuit serial programming (ICSP), dedicate RB6 and RB7 (pins 12-13) to the ICSP clock and data lines without series resistors above 100 ohm to ensure reliable programming. Use a ground plane beneath the SSOP package to reduce EMI and improve thermal dissipation.
OTP (One-Time Programmable) memory cannot be erased or rewritten - a single bad programming cycle or code revision requires scrapping the unit. Always verify code in PIC16F Flash prototypes (e.g., PIC16F628A) before committing to OTP production. Note that PIC16CE62X devices use the mid-range instruction set, and code written for PIC16Cxxx baseline devices must be reviewed for compatibility. Brown-out reset configuration fuse must be enabled for reliable startup in noisy industrial environments.
When using the analog comparators (pins RA0-RA3 for inputs), decouple the analog reference voltage with a 100 nF capacitor and avoid routing digital switching signals within 3 mm of the comparator inputs. The internal bandgap reference is shared with both comparators and may show 5-10 mV noise if VDD is poorly regulated. For PWM output using the CCP module (RB3), place a series 100 ohm resistor close to the pin to dampen ringing into long cables or motor windings.
