NXP Semiconductors MC9S08QE96CLH

Overview

MC9S08QE96CLH from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 96 KB flash, 6 KB RAM, 64-pin LQFP package, and integrated 22-channel 12-bit ADC, dual analog comparators, dual SCI/LIN, dual SPI, dual I²C, triple TPM modules, RTC, and background debug interface. It operates up to 50.33 MHz at ≥2.4 V and supports automotive and industrial control applications requiring low-power operation and mixed-signal integration.

For engineers reviewing the MC9S08QE96CLH datasheet, MC9S08QE96CLH pinout, MC9S08QE96CLH application, or MC9S08QE96CLH equivalent, key selection considerations include its 64-pin LQFP mechanical compatibility, 1.8–3.6 V supply range, stop-mode wake-up time ≤6 μs, 22-channel ADC with temperature sensor, and support for LIN bus master/slave functionality in embedded control systems.

Technical Context

The MC9S08QE96CLH implements the HCS08 CPU core with HC08 instruction set extension (BGND), supporting up to 32 interrupt/reset sources and FLL-based internal clock source (ICS) with ±2% deviation and 0.2% trimming resolution. Its system architecture integrates dedicated peripherals including two SCIs with LIN break generation/detection, two I²C modules supporting 100 kbps and multi-master operation, and three timer/PWM modules (TPM1: 3-channel, TPM2: 3-channel, TPM3: 6-channel).

Power management includes two low-power stop modes, reduced-power wait mode, peripheral clock gating via PCE register, and a very low-power external oscillator option for stop3 mode. The device features on-chip security circuitry, flash block protection, COP watchdog with selectable 1-kHz or bus-clock source, and low-voltage detection with programmable trip points (VLVDH/VLVDL).

FAQ

What is the maximum operating frequency of the MC9S08QE96CLH and at what supply voltage?

The MC9S08QE96CLH achieves up to 50.33 MHz when supplied at ≥2.4 V, 40 MHz at ≥2.1 V, and 20 MHz down to 1.8 V across the full –40°C to +85°C temperature range. This voltage-frequency scaling allows dynamic performance adjustment based on battery level or thermal conditions while maintaining deterministic real-time behavior in the MC9S08QE96CLH.

Does the MC9S08QE96CLH support LIN communication natively, and which peripherals enable it?

Yes, the MC9S08QE96CLH supports LIN 2.x natively through its two SCI modules, which provide LIN master extended break generation and LIN slave extended break detection. No external LIN transceiver is required for basic node operation, though physical layer compliance still requires an external LIN driver such as the MC33661 or TJA1020. This capability is implemented directly in the MC9S08QE96CLH's SCI hardware.

How many analog-to-digital converter (ADC) channels does the MC9S08QE96CLH have, and what is their resolution and conversion time?

The MC9S08QE96CLH features a 22-channel, 12-bit successive approximation register (SAR) ADC with a typical conversion time of 2.5 μs. It includes an internal temperature sensor (1.7 mV/°C), bandgap reference channel, and automatic compare function. Operation is fully supported in stop3 mode, enabling low-power sensor polling without waking the CPU - a key capability of the MC9S08QE96CLH for battery-operated systems.

What debug interface does the MC9S08QE96CLH provide, and is external hardware required?

The MC9S08QE96CLH provides a single-wire background debug (BKGD) interface on pin PTA4, supporting in-circuit debugging, flash programming, and breakpoint setting without requiring a full JTAG pod. An external debug adapter such as the OSBDM or Cyclone MAX is needed to connect to a host PC, but no target-side JTAG header or additional pins are necessary - this streamlined debug architecture is integral to the MC9S08QE96CLH design.

What package type and pin count does the MC9S08QE96CLH use, and is it RoHS compliant?

The MC9S08QE96CLH uses a 64-pin LQFP package (Case 840F, 10 mm² footprint) with exposed pad for thermal dissipation. It is RoHS compliant and lead-free, meeting JEDEC standards for moisture sensitivity level (MSL) 3. This package is mechanically and electrically compatible with other members of the MC9S08QE128 series, enabling scalable design reuse across the MC9S08QE96CLH and related variants.
