Product details
Overview
MC9S08SE8VWL from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 8 KB flash, 512 bytes RAM, 20 MHz CPU, 10 MHz bus frequency, and integrated peripherals including 10-bit ADC, dual TPM timers, SCI with LIN support, RTC, and KBI. It targets low-power industrial control, sensor interface, and automotive body electronics where compact footprint and robust power management are critical.
For engineers reviewing the MC9S08SE8VWL datasheet, MC9S08SE8VWL pinout, MC9S08SE8VWL application, or MC9S08SE8VWL equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options - all grounded in Freescale's Rev. 4 (2015) official datasheet and mechanical drawings for the 28-pin SOIC variant (Case 751F).
Technical Context
The MC9S08SE8VWL implements the HCS08 CPU core with HC08 instruction set extension (BGND), supporting up to 32 interrupt/reset sources and single-wire background debug. Its clock system combines a precision internal clock source (ICS) with FLL-based frequency locking and external crystal/resonator support (31.25 kHz–16 MHz), enabling stable bus frequencies from 1–10 MHz across voltage and temperature.
Peripherals include a 10-channel 10-bit ADC with 2.5 μs conversion time, temperature sensor (1.7 mV/°C), and bandgap reference; two timer/pulse-width modulator modules (TPM1: 2-channel, TPM2: 1-channel); full-duplex SCI with LIN master/slave break generation; real-time counter; and 8-pin keyboard interrupt module - all operable in Stop3 mode for ultra-low-power operation.

Does the MC9S08SE8VWL support in-system programming via its debug interface?
Yes, the MC9S08SE8VWL supports in-circuit programming and debugging through its single-wire background debug (BDC) interface using the BKGD/MS pin, enabling firmware updates and real-time trace without removing the device from the target board.
Can the MC9S08SE8VWL's ADC operate while the MCU is in Stop3 mode?
Yes, the MC9S08SE8VWL's 10-bit ADC is explicitly specified to run in Stop3 mode per datasheet Section 2 and Table 11, allowing low-power periodic sensor sampling without waking the CPU - critical for battery-operated applications.
What clock sources are available for the MC9S08SE8VWL's internal clock system?
The MC9S08SE8VWL supports two primary clock sources: an external crystal/resonator via PTB7/PTB6 (XOSC, 31.25 kHz–16 MHz), and an internal clock source (ICS) with FLL-based frequency locking and factory/user trimming for 1–10 MHz bus frequencies.
Is the MC9S08SE8VWL pin-compatible with other devices in the S08SE family?
The MC9S08SE8VWL shares identical pinout and package (28-pin SOIC) with MC9S08SE4VWL per datasheet Table 1 and Figures 2–3, differing only in flash (8 KB vs. 4 KB) and RAM (512 B vs. 256 B) - enabling direct substitution where memory requirements align.
