NXP Semiconductors MC9S08QE96CLK

Overview

MC9S08QE96CLK from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 96 KB flash, 6 KB RAM, 64-pin LQFP package, and integrated peripherals including dual SCI, dual SPI, dual I²C, six-channel TPM, RTC, 22-channel 12-bit ADC, and two analog comparators. It operates up to 50.33 MHz at ≥2.4 V and supports automotive-grade temperature range (–40°C to +85°C) for engine control and body electronics applications.

For engineers reviewing the MC9S08QE96CLK datasheet, MC9S08QE96CLK pinout, MC9S08QE96CLK application, or MC9S08QE96CLK equivalent, this page delivers verified electrical specs, package mapping, functional pin roles, real-world use cases, and validated alternative parts - all grounded in Freescale's official MC9S08QE128 Series Data Sheet Rev. 7 and QFN Addendum Rev. 0.

Technical Context

The MC9S08QE96CLK implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources and operating across three voltage-dependent frequency tiers: 50.33 MHz (≥2.4 V), 40 MHz (≥2.1 V), and 20 MHz (≥1.8 V). Its internal clock source (ICS) uses FLL with factory-trimmed internal reference (0.2% resolution, ±2% deviation) to generate CPU clocks from 2–50.33 MHz.

System-level timing is managed via multiple clock domains: external crystal/ceramic oscillator (XOSC) supporting 31.25 kHz–16 MHz, low-power RTC oscillator (1 kHz), and stop-mode-compatible very-low-power external oscillator. Peripheral clock gating via PCE (Peripheral Clock Enable) register enables selective module power-down without affecting active functions like RTC or ACMP in STOP3 mode.

Key Specifications

Pinout & Package

MC9S08QE96CLK is packaged in 64-pin LQFP (Case 840F, 10 mm² footprint) with exposed pad for thermal management. Pin assignments follow the MC9S08QE128 series standard; all pins support configurable pull-up, hysteresis, slew rate, and drive strength. VDD/VSS pins are internally connected to dual pads per Freescale's QFN/LQFP design practice.

FAQ

What is the maximum operating frequency of the MC9S08QE96CLK and under what voltage conditions?

The MC9S08QE96CLK achieves up to 50.33 MHz when supplied at ≥2.4 V, 40 MHz at ≥2.1 V, and 20 MHz at ≥1.8 V across the full –40°C to +85°C temperature range. These frequency tiers are enforced by internal voltage monitoring and are specified in the MC9S08QE128 Series Data Sheet Rev. 7 Section 1. The actual bus frequency is derived from the ICS or XOSC source and divided per configuration registers.

Does the MC9S08QE96CLK support LIN communication, and how is it implemented?

Yes, the MC9S08QE96CLK supports LIN 2.0/2.1 master and slave operation through its dual SCI modules. SCI1 and SCI2 each provide extended break generation (master) and extended break detection (slave), along with wake-up-on-active-edge functionality. This is implemented in hardware without CPU intervention, enabling low-power LIN node operation in STOP3 mode as documented in the MC9S08QE128 Series Data Sheet Rev. 7 Section 1.

What package type and pin count does the MC9S08QE96CLK use, and is it pin-compatible with other devices in the QE series?

The MC9S08QE96CLK uses a 64-pin LQFP package (Case 840F, 10 mm²). It is pin-compatible with the MC9S08QE128CLK in the 64-pin variant - sharing identical pin assignments, peripheral mappings, and electrical characteristics per Table 2 of the MC9S08QE128 Series Data Sheet Rev. 7. This allows direct substitution where flash/RAM requirements permit.

How does the MC9S08QE96CLK handle power management during low-power operation?

The MC9S08QE96CLK supports multiple low-power modes: two stop modes and a reduced-power wait mode. In STOP3 mode, the CPU and most clocks halt while RTC, ACMPs, and selected peripherals remain active; wake-up occurs in 6 μs. Peripheral clocks can be individually disabled via the PCE register, and a very-low-power external oscillator sustains accurate timing for active modules - all detailed in Section 1 of the MC9S08QE128 Series Data Sheet Rev. 7.

What analog features are integrated into the MC9S08QE96CLK, and how many channels does the ADC support?

The MC9S08QE96CLK integrates a 22-channel, 12-bit successive-approximation ADC with 2.5 μs conversion time, automatic compare function, internal temperature sensor (1.7 mV/°C), and internal bandgap reference channel. It also includes two analog comparators (ACMP1, ACMP2) with selectable interrupt edges and routing to TPM modules. All analog functions operate in STOP3 mode, as confirmed in the MC9S08QE128 Series Data Sheet Rev. 7 Section 1 and Table 1.
