PIC16C58BT-04E/SS - 8-Bit 4MHz OTP MCU 3KB | Microchip
The Microchip Technology PIC16C58BT-04E/SS is an EPROM/ROM-based 8-bit CMOS microcontroller in the PIC® 16C5X family, delivering 4MHz maximum clock speed with 3KB (2K x 12) of One-Time Programmable (OTP) program memory in a 20-pin SSOP package. It is a low-cost, high-performance, fully static RISC device with 33 single-word/single-cycle instructions, providing 12 I/O pins, 73 bytes of RAM, an integrated Power-On Reset (POR), and a Watchdog Timer (WDT).
An 8-bit microcontroller is a single-chip computer that integrates a CPU, RAM, non-volatile program memory, and I/O peripherals on one die. RISC (Reduced Instruction Set Computer) microcontrollers like the PIC16C5X family use a small, fixed-length instruction set — typically 33 to 35 instructions — where most instructions execute in a single clock cycle. This makes them far more deterministic and easier to program than CISC designs. In the broader system hierarchy, the PIC16C5X belongs to the microcontroller family, which sits within the embedded computing category of digital ICs, used everywhere from appliance controls to industrial sensors.
Key features of the PIC16C58BT-04E/SS include: 2:1 code compression versus competing 8-bit MCUs, a wide operating voltage range, ultra-low power CMOS design, and an industrial temperature grade of -40°C to +125°C. The 4MHz oscillator, combined with 12-bit-wide instructions, yields compact code density. Its 20-pin SSOP package offers a small board footprint suitable for space-constrained designs, and the -04 speed variant specifies the 4MHz maximum frequency, while the 'E' suffix denotes the extended industrial temperature range.
Technically, the PIC16C58B uses a Harvard architecture with separate program and data buses, allowing instruction fetch and data access in a single cycle. The 12-bit instruction word is the hallmark of the PIC16C5X baseline architecture, distinct from the 14-bit mid-range and 16-bit enhanced cores. With 73 bytes of general-purpose RAM and 12 digital I/O pins, the device targets simple control loops, user-interface logic, and glue-replacement tasks rather than high-throughput signal processing.
Typical applications for the PIC16C58BT-04E/SS include appliance control (washing machines, microwaves, coffee makers), battery chargers, LED lighting controllers, simple sensor interfaces, and remote-control transmitters. Its OTP memory is suited to high-volume production where firmware is finalized and re-programming is unnecessary. The device is also commonly used in educational platforms and legacy industrial equipment retrofits.
When designing with the PIC16C58BT-04E/SS, engineers should plan around the OTP memory constraint: firmware must be 100% verified before programming, as OTP parts cannot be re-flashed. The 4MHz limit and 2K x 12 program word count also bound the algorithmic complexity; tasks requiring floating-point math or large lookup tables may need the PIC16C55, PIC16C56, or PIC16C57 siblings with more program memory.
