On-chip peripherals include a low-voltage detect (LVD), power-on reset (POR), PWM timer, and watchdog timer (WDT) — these cover basic supervisory and timing functions that would otherwise require external reset ICs or watchdogs, reducing BOM count. The single SCI (UART) serial interface handles point-to-point communication with a host controller, sensor module, or debug terminal. No I²C or SPI on this part — if those buses are needed, the 40 MHz S08 peers like the MC9S08GT8AMFDE add them. ## Package and board-fit — 32-LQFP 7x7 mm The supplier device package is 32-LQFP (7x7), matching the package/case field exactly. Mounting is surface-mount only. The package is ROHS3 compliant. No exposed thermal pad — the 0.8 mm pitch leads handle the heat dissipation; no special soldering profile beyond standard lead-free reflow. ## Sourcing posture — active, quoted to order The closest pin-compatible peer is the MC9S08RE8FJE, which halves the flash to 8 KB but shares the same 32-LQFP package, pinout, and peripheral set — a drop-in replacement if the firmware fits in the smaller memory.","metaTitle":"NXP MC9S08RE16FJE S08 MCU, 8MHz, 16KB Flash, 32-LQFP","metaDescription":"NXP MC9S08RE16FJE 8-bit MCU, S08 core at 8MHz, 16KB flash, 1KB RAM, 25 I/O, 32-LQFP.
