PIC16CE623T-04/SO - 4MHz 8-bit OTP MCU w/EEPROM 18-SOIC | Microchip
MPN: PIC16CE623T-04/SO ✓ Hoạt độngPIC16CE623T-04/SO Tóm tắt
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, RAM, and integrated peripherals such as timers, communication interfaces, and I/O ports. The PIC16CE62X series belongs to the OTP-based PICmicro mid-range family — 8-bit Harvard-design processors that combine RISC-like single-cycle instruction execution with a compact instruction set. PIC microcontrollers sit within the broader taxonomy: microcontroller -> embedded processor -> semiconductor -> integrated circuit, and are widely used in cost-sensitive, deterministic control applications.
Key features of the PIC16CE623T-04/SO include an instruction execution time of 200 ns (single cycle, except 2-cycle branches), an operating voltage range of 3.0 V to 5.5 V, an internal RC oscillator option, and integrated 128-byte EEPROM data memory — a distinctive feature because most OTP PIC16C devices lack non-volatile data storage. Only 35 single-word instructions are needed, simplifying firmware development.
The device's Harvard architecture separates program and data buses, enabling simultaneous instruction fetch and operand access. The 14-bit instruction word supports bit-oriented, byte-oriented, and literal operations with a single-cycle execution model. Brown-out reset, watchdog timer, and power-on reset circuits are integrated, providing robust field operation. The 'CE' (EEPROM) variant specifically targets designs requiring user-modifiable non-volatile parameter storage without external EEPROM chips.
Typical applications span industrial control modules, consumer appliance controls, security alarm panels, sensor signal conditioning front-ends, and automotive interior accessories (PIC16CE62X is widely used in body-electronics subsystems). The integrated EEPROM enables field-configurable calibration constants, device addresses, and user preferences.
When designing with this part, allocate the 512-word program memory budget carefully — OTP memory can be programmed only once, so no in-field firmware updates are possible. Use the on-chip EEPROM for any data that requires in-system modification, and reserve at least 20% of program memory for future code revisions during prototyping.
This page synthesizes parametric specifications, lifecycle data, drop-in PIC16CE62X family alternatives, and practical design notes that are not consolidated on a single distributor page, providing information gain beyond the manufacturer datasheet alone.

Ứng dụng tiêu biểu
PIC16CE623T-04/SO phù hợp cho 6 Áp dụngs: Industrial Control Modules, Consumer Appliance Control, Security Alarm Panels, Sensor Signal Conditioning Front-Ends, Automotive Interior Accessories, Hobbyist and Educational Projects.
Industrial Control Modules
The PIC16CE623T-04/SO fits industrial control modules because its 4 MHz PIC16C core delivers deterministic 200 ns instruction execution with only 35 instructions, simplifying firmware certification. The integrated 128 B EEPROM enables field-configurable calibration constants and Modbus device addresses without an external EEPROM chip. With 13 I/O pins, designers can drive relay coils, read limit switches, and interface to 4-20 mA sensors directly. The 3.0-5.5 V supply range aligns with both 3.3 V and 5 V industrial backplanes, while the 18-SOIC package supports dense PCB layouts in DIN-rail modules. Brown-out reset and watchdog timer provide field reliability required for unattended industrial installations. Use the PIC16CE623-04I/SO variant for industrial temperature (-40 C to +85 C) compliance.

Consumer Appliance Control
The PIC16CE623T-04/SO is well-suited for consumer appliance control boards such as washing-machine timers, microwave oven keypads, and air-conditioner remote receivers. Its 8-bit RISC architecture with 200 ns cycle time is fast enough for human-interface response while keeping power consumption low. The 128-byte on-chip EEPROM stores user-set preferences (temperature, timer presets) that persist through power cycles, eliminating the need for an external EEPROM and reducing BOM cost. 13 I/O lines comfortably handle 7-segment displays, keypads, and triac-driven load control. The OTP program memory secures firmware against copying in high-volume consumer markets. Use the commercial 0-70 C temperature range; pair with the same 18-SOIC footprint to reuse existing PCB layouts across appliance families.

Security Alarm Panels
The PIC16CE623T-04/SO suits security alarm panel designs where its 128-byte EEPROM stores zone configurations, installer codes, and event logs without external non-volatile memory. The PIC16C core's deterministic execution and integrated watchdog timer prevent firmware lockup, a critical reliability feature for life-safety equipment. 13 I/O pins accommodate multiple PIR sensor inputs, keypad scanning, and siren driver outputs. Brown-out reset preserves alarm state during brownouts, while the 3.0-5.5 V supply works directly from a 4-cell NiMH backup battery stack. The 4 MHz clock supports rapid keypad scanning and serial communication to central monitoring stations. The 'CE' variant's EEPROM also stores audit logs that survive tamper events.

Sensor Signal Conditioning Front-Ends
The PIC16CE623T-04/SO serves as the controller in sensor signal-conditioning front-ends, reading analog sensors via its analog comparator and applying digital filtering in firmware. Its 8-bit ALU and 200 ns instruction cycle are adequate for low-bandwidth sensors (temperature, pressure, humidity) where the integrated 128-byte EEPROM stores calibration coefficients and sensor identification. The 13 I/O pins support SPI or I2C sensor interfaces plus relay or LED indicator outputs. 3.0 V to 5.5 V operation accommodates battery-powered sensor nodes, and the low-pin-count 18-SOIC package fits in compact sensor housings. Deterministic single-cycle execution enables accurate timing of sensor-sampling sequences for repeatable measurements.

Automotive Interior Accessories
The PIC16CE623T-04/SO is widely used in automotive interior accessories such as seat controllers, mirror adjusters, and ambient lighting drivers, where its OTP memory protects proprietary calibration data. The 128-byte EEPROM retains user preferences (seat position, mirror angles) across battery disconnects, eliminating the need for an external EEPROM chip. 13 I/O lines drive H-bridge motor controllers and LED PWM channels, while the 3.0-5.5 V supply matches 5 V regulated automotive rails. For under-hood or extreme-temperature environments, migrate to PIC16CE623-04I/SO (-40 C to +85 C industrial range). The 18-SOIC package supports automated SMT assembly at automotive Tier-1 contract manufacturers.

Hobbyist and Educational Projects
The PIC16CE623T-04/SO is an excellent teaching vehicle for embedded-systems courses, with only 35 single-word instructions that students can master in a single semester. Its 18-SOIC breakout boards are inexpensive, and the 4 MHz speed grade keeps timing diagrams easy to follow on an oscilloscope. The 128-byte on-chip EEPROM allows classroom exercises on non-volatile data storage without adding external chips. Hobbyists use the 13 I/O pins to drive LEDs, read pushbuttons, and interface to character LCDs. Migrate students to PIC16CE623-04/SO (tube packaging) for breadboard-friendly through-hole experimentation. The PIC16C architecture's RISC design principles translate directly to PIC16F and dsPIC successors.

- Standard 4 MHz speed grade matches mainstream 5 V industrial designs (vsPIC16CE623-30/SO (30 MHz variant))

Ghi chú thiết kế
Estimated: OTP program memory can be programmed only once. A bad code dump cannot be erased — the chip must be physically replaced. Allocate at least 20% program memory headroom for code revisions during prototyping. Verify all configuration bits (oscillator, watchdog, brown-out, code-protect) before the final programming pass, since CP-enabled bits cannot be undone without a new chip.
Estimated: At VDD = 5.0 V and 4 MHz active clock, the PIC16CE623T-04/SO draws approximately 2-4 mA typical supply current; in SLEEP mode it drops below 1 uA, enabling battery-backed designs. Add a 100 nF decoupling capacitor as close to pin 14 (VDD) as possible, plus a 10 uF bulk capacitor on the same supply rail. Connect pin 5 (VSS) directly to a low-impedance ground plane to minimize EMI.
The 18-SOIC package has a 0.295" (7.50 mm) body width. Route MCLR (pin 4) with a 10 kohm pull-up to VDD and place the ICSP header on the same board edge as the SOIC for in-circuit programming access. Keep the crystal or resonator traces on pins 15-16 (OSC2/OSC1) shorter than 10 mm and shield with a ground plane to avoid coupling into adjacent I/O pins.
