Packaging

Type: Package/Case per listing 1057; common PIC16F57 variants are offered in PDIP-28 (through-hole), SOIC-28, and SSOP-28 (surface-mount). Confirm exact case for your SKU on the datasheet.

Material: Molded epoxy body with copper leadframe; lead finish typically matte-tin for RoHS options

Size: 28-pin footprints; PDIP standard 300 mil body, SOIC/SSOP with 1.27 mm pitch (SOIC) or finer (SSOP). Verify exact dimensions in the datasheet mechanical section.

Pin configuration: PIC16F5x family pinout with multiple GPIO; pin-compatible across family variants when package matches. Check pin mapping before drop-in replacement.

Thermal characteristics: Commercial and industrial grades available; typical operating ambient -40°C to +85°C. Junction-to-ambient values depend on package and board; see datasheet thermal data.

Electrical properties: 5V-class operation, low standby current, WDT, sleep; external clock up to typical MCU limits. Refer to datasheet for voltage ranges, currents, and timing.

Lifecycle

Status: Generally an active/mature Microchip PIC16 family device. Not flagged as near end-of-life at our last review. For the latest status, check our product page or contact us.

Equivalent or alternative models:

- PIC16F54: Baseline PIC, smaller memory and feature set; similar family, check pinout

- PIC16F55: Baseline PIC, variant with different I/O and memory

- PIC16F56: Baseline PIC, mid-range within the 16F5x series

- PIC16F58: Baseline PIC, expanded features vs 54/55/56; verify compatibility

- PIC16F59: Higher I/O count in the same family; not always pin-compatible

- Package-specific variants such as PIC16F57-I/P (PDIP), PIC16F57-I/SO (SOIC), PIC16F57-I/SS (SSOP)

Always verify pinout, memory size, peripherals, and timing against your design. If you need exact drop-in or form-fit-function replacements and do not see a match, please contact our sales team via our website for tailored guidance.
