MC9S08QE32CLC

Product Overview

The MC9S08QE32CLC from NXP USA Inc. is an 8-bit S08 core microcontroller in a 32-LQFP (7x7) surface-mount package. It provides 32KB (32K x 8) FLASH program memory, 2K x 8 RAM, and 26 I/O pins. The device operates at 50MHz with an internal oscillator and supports a supply voltage range of 1.8V to 3.6V. Communication interfaces include I2C, LINbus, SCI, and SPI, while peripherals include LVD, PWM, and WDT. The 10x12b A/D converters and -40°C to 85°C (TA) operating temperature range define its embedded control context.

Design & Procurement Notes

Board designers should account for the 32-LQFP (7x7) surface-mount footprint, 26 I/O pins, and 1.8V to 3.6V supply range when selecting power and signal conditioning. The internal oscillator simplifies clocking, while I2C, LINbus, SCI, and SPI interfaces support mixed serial peripherals. PWM, LVD, WDT, and 10x12b A/D resources should be mapped to control loops, protection, and sensor inputs. The -40°C to 85°C (TA) range and 32KB FLASH/2K x 8 RAM should be evaluated against firmware size and environmental requirements.
