Product details
Overview
MC9S08QE128CFTR from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 128 KB flash, 8 KB RAM, and 70 GPIOs in a 48-pin QFN package. It operates up to 50.33 MHz above 2.4 V, features dual analog comparators, a 24-channel 12-bit ADC with 2.5 μs conversion time, and supports LIN-compliant SCI interfaces for automotive body control modules.
For engineers reviewing the MC9S08QE128CFTR datasheet, MC9S08QE128CFTR pinout, MC9S08QE128CFTR application, or MC9S08QE128CFTR equivalent, key selection criteria include its 48-QFN thermal performance (θJA = 81°C/W on single-layer board), stop-mode wake-up time (6 μs), real-time counter with 1 kHz low-power oscillator, and integrated security circuitry for flash/RAM protection.
Technical Context
The MC9S08QE128CFTR 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 2–50.33 MHz.
System-level timing is managed via three timer/PWM modules: TPM1 (3-channel), TPM2 (3-channel), and TPM3 (6-channel), all supporting input capture, output compare, and edge- or center-aligned PWM. The RTC provides 8-bit modulus counting with binary/decimal prescaler and external clock input for calendar/time-of-day functions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08AC128CPUE | Same HCS08 core, 128 KB flash, but 64-pin LQFP; lacks second I²C and one SCI; no RTC | Targeted at non-time-critical control where PCB space allows larger package and RTC not required | Select when needing higher I/O count (54 GPIOs) and simpler peripheral set without LIN or RTC dependencies |
| S9KEAZ128AMLH | Kinetis E-series ARM Cortex-M0+, 128 KB flash, 16 KB RAM, 48-QFN; higher performance but different toolchain and power profile | Migration path for designs scaling beyond 8-bit throughput or requiring CAN/LPUART | Choose for future-proofing with ARM ecosystem; requires redesign due to architecture and peripheral incompatibility |
Compared with MC9S08AC128CPUE, MC9S08QE128CFTR delivers LIN-ready dual SCI and RTC in a smaller 48-QFN footprint; versus S9KEAZ128AMLH, it offers lower system cost and deterministic 8-bit real-time response but lacks ARM scalability and CAN support.

FAQ
What is the maximum operating frequency of the MC9S08QE128CFTR and under what voltage conditions?
The MC9S08QE128CFTR achieves up to 50.33 MHz when VDD ≥ 2.4 V, 40 MHz at VDD ≥ 2.1 V, and 20 MHz at VDD ≥ 1.8 V, across the full industrial temperature range (–40°C to +85°C). These ratings are guaranteed per Rev. 7 datasheet Section 1 and confirmed in electrical characteristics tables.
Does the MC9S08QE128CFTR support LIN communication natively, and which peripherals enable it?
Yes, the MC9S08QE128CFTR supports LIN 2.x natively through its two SCI modules: SCI1 and SCI2 each provide LIN master extended break generation and LIN slave extended break detection. No external transceiver is needed for basic node implementation, as confirmed in the "SCIx" feature list of the Rev. 7 datasheet.
What package type and thermal characteristics apply to the MC9S08QE128CFTR?
The MC9S08QE128CFTR uses a 48-pin QFN package (Case 1314, 7 mm²) with copper wire bonding per Freescale QFN Addendum Rev. 0. Its thermal resistance is θJA = 81°C/W on single-layer board and 26°C/W on four-layer board, enabling reliable operation in thermally constrained automotive and industrial enclosures.
How many analog-to-digital converter channels does the MC9S08QE128CFTR have, and what is their resolution and speed?
The MC9S08QE128CFTR integrates a 24-channel, 12-bit ADC with 2.5 μs conversion time per sample, fully operational from 1.8 V to 3.6 V. It includes an internal temperature sensor (1.7 mV/°C), bandgap reference channel, and automatic compare function - all functional in stop3 mode per Rev. 7 datasheet Section 1.
Is the MC9S08QE128CFTR pin-compatible with other members of the QE128 series, such as the 80-pin LQFP variant?
No, the MC9S08QE128CFTR (48-pin QFN) is not pin-compatible with the 80-pin LQFP MC9S08QE128CLH. Pin assignments differ significantly: the 48-pin version omits ports G, H, J, and several analog/digital pins present in larger packages. Migration requires PCB redesign and signal mapping per Table 2 in Rev. 7 datasheet.
