PIC16C715T-04I/SS
PIC16C715T-04I/SS - 8-Bit PIC MCU, 3.5KB OTP, 4MHz, 20-SSOP
The Microchip PIC16C715T-04I/SS is a CMOS, fully-static, 8-bit PIC microcontroller from the PIC16C71X family, supplied in a 20-pin SSOP (Shrink Small Outline Package) on tape-and-reel. The "T" suffix denotes tape-and-reel packaging, "04" indicates a 4 MHz maximum oscillator frequency, "I" denotes the industrial temperature range (-40C to +85C), and "/SS" specifies the SSOP package. The device integrates 3.5 KB of one-time-programmable (OTP) program memory, 128 bytes of data RAM, 13 digital I/O pins, and a 4-channel 8-bit analog-to-digital converter (ADC), making it suitable for mixed-signal embedded applications.
An 8-bit microcontroller (MCU) is a single-chip computer that combines a CPU, program memory (ROM/EPROM/Flash/OTP), working RAM, and peripherals such as timers, ADC, and I/O ports. The PIC16C71X family belongs to Microchip's mid-range PIC architecture (14-bit instruction word), sitting above the baseline PIC16C5X in instruction set power and below the PIC18 family in performance. This hierarchy (OTP-based 8-bit MCU -> PIC mid-range -> 8-bit microcontroller family -> embedded MCU category) makes the PIC16C715 a workhorse for cost-sensitive, low-power control applications.
Key features include 200 ns instruction execution time (5 MIPS at 4 MHz), 35 single-word instructions, an 8-level deep hardware stack, four interrupt sources, and a programmable code-protection bit. The 8-bit ADC delivers 4 channels with selectable reference voltages, supporting sensor and signal-acquisition tasks. The CMOS process delivers low power consumption suitable for battery-operated and industrial embedded designs.
Architecturally, the device uses a Harvard bus architecture with separate program and data paths, enabling simultaneous instruction fetch and operand access. The RISC-style 35-instruction set simplifies code development while supporting bit-level manipulation, a hallmark of PIC microcontrollers. Two 8-bit timer/counters and one 16-bit timer/counter provide flexible event timing, while the watchdog timer enhances system reliability.
Typical applications include sensor signal conditioning, simple motor control, white goods and appliance control, industrial automation peripherals, and battery-powered instrumentation. The industrial temperature range and integrated ADC make it well suited for harsh-environment embedded systems.
When designing with this device, note that OTP program memory requires one-time programming during manufacturing and cannot be field-updated; for prototype or low-volume production, consider the flash-based PIC16F716 equivalent recommended by Microchip. Brown-out reset, power-on reset, and watchdog timer features must be configured by firmware for robust operation.
