Product details
Overview
MC9S08QE96CLD from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 96 KB flash, 6 KB RAM, and 64-pin LQFP package. It features a 50.33-MHz CPU (at ≥2.4 V), dual analog comparators, 22-channel 12-bit ADC, two I²C/SPI/SCI interfaces, six-channel TPM, RTC, and low-power stop modes - used in industrial sensor nodes and motor control subsystems.
For engineers reviewing the MC9S08QE96CLD datasheet, MC9S08QE96CLD pinout, MC9S08QE96CLD application, or MC9S08QE96CLD equivalent, key selection criteria include its 64-pin LQFP footprint, 1.8–3.6 V operation, integrated security circuitry, single-wire background debug interface, and support for LIN-compliant SCI peripherals in automotive body electronics.
Technical Context
The MC9S08QE96CLD implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources. Its internal clock source (ICS) uses FLL with factory-trimmed internal reference (0.2% resolution, ±2% deviation) to generate CPU frequencies from 2 MHz to 50.33 MHz across voltage and temperature.
System-level timing relies on multiple clock domains: external crystal/ceramic oscillator (31.25 kHz–16 MHz), internal 1-kHz low-power RTC oscillator, and bus-synchronized peripherals including two SCIs with LIN master/slave break generation, two SPIs with double-buffered TX/RX, and three TPM modules supporting input capture, output compare, and edge- or center-aligned PWM.
