It carries 8 KB of Flash program memory and 512 bytes of RAM. On-chip peripherals include a 10-channel 10-bit ADC, LINbus and SCI serial interfaces, plus LVD, POR, and PWM. The 24 I/O pins in a 28-SOIC package give enough headroom for a LIN transceiver, a few analog sensors, and a small display or keypad. The -40°C to 85°C temperature range qualifies it for outdoor telecom, factory-floor controllers, and automotive cabin-adjacent modules. ## Memory and speed — what fits, what doesn't The 20 MHz clock is the headline performance rating for this 8-bit S08 core — it sets the timing budget for LIN/SCI communication and PWM update rates. The 8 KB Flash defines the firmware footprint ceiling: enough for a small LIN node or sensor hub, not for a multi-protocol gateway. The 512 bytes RAM constrains the buffer depth for SCI frames and ADC conversions — a key BOM-fit check against the application's data memory requirement. ## Package and rework — 28-SOIC is a bench-friendly footprint The 28-SOIC package (7.50 mm body) is a surface-mount footprint. The 0.295-inch width gives good pad access for hand-soldering or reflow touch-up.","metaTitle":"NXP MC9S08SE8CWL 8-bit MCU, 20 MHz, 8 KB Flash, 28-SOIC","metaDescription":"NXP MC9S08SE8CWL 8-bit S08 MCU with 20 MHz core, 8 KB Flash, 512 B RAM, LIN/SCI, 10-bit ADC, -40°C to 85°C.
