The NXP MC9S08RE8FJE is an 8-bit microcontroller built around the S08 core, with 8 KB of on-chip Flash program memory and 25 general-purpose I/O lines. It runs at 8 MHz and operates from a 1.8 V supply, making it a low-voltage, low-pin-count choice for cost-sensitive control applications. The part includes a serial communications interface (SCI), plus a low-voltage detect (LVD), power-on reset (POR), PWM, and watchdog timer (WDT) on the peripheral set.
Package and supply — 32-LQFP, 1.8 V only
Housed in a 32-lead LQFP, the part is surface-mount and uses a 1.8 V supply rail. The 25 I/O count in a 32-pin package means most pins are available for GPIO, but check the pinout against your schematic — the SCI and PWM functions share pins with the I/O.
