Product details

Core specs and memory budget for the BOM line

The Microchip PIC16F18857T-I/ML is an 8-bit MCU from the PIC® XLP™ 16F series with a Functional Safety (FuSa) designation, running at 32 MHz. It packs 56 KB (32K x 14) of Flash program memory, 4 KB (4K x 8) of RAM, and 256 bytes of EEPROM — enough for moderate sensor-fusion or control loops without external storage.

On-chip data converters (24-channel 10-bit ADC, one 5-bit DAC) handle analog inputs without an external ADC.

ROHS3 compliant — no special handling for lead-free reflow.

Frequently asked questions

What is the difference between PIC16F18857T-I/ML and PIC16F18857-I/ML?

The only difference is the packaging medium: the 'T' suffix denotes Tape & Reel (or Cut Tape) shipping, while the non-T version ships in tubes or trays. The die, firmware, and electrical specs are identical.

Does PIC16F18857T-I/ML support functional safety (FuSa) features?

Yes, it is part of the PIC® XLP™ 16F series with a Functional Safety (FuSa) designation. This indicates the MCU includes hardware features and documentation to support functional safety designs, though the specific safety manual and FMEDA should be reviewed for your application.

Can PIC16F18857T-I/ML replace an existing PIC16F18857-I/ML in my design?

Yes, the two are electrically and functionally identical — the only difference is the shipping medium. You can drop the T-suffix version into the same PCB without any firmware or hardware changes.
