Product details
Overview
MC9S08QE4CTGR from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 4 KB flash, 256 B RAM, 20 MHz CPU operation at 1.8–3.6 V, integrated 12-bit ADC, dual analog comparators, and SPI/I²C/SCI peripherals - used in low-power industrial sensor nodes and automotive body electronics.
For engineers reviewing the MC9S08QE4CTGR datasheet, MC9S08QE4CTGR pinout, MC9S08QE4CTGR application, or MC9S08QE4CTGR equivalent, this page delivers verified package mapping (32-pin QFN), confirmed stop3-mode current (0.4–6 µA), real-time counter with 1 kHz LPO, single-wire background debug interface, and validated alternative part selection for cost-optimized 8-bit MCU replacement.
Technical Context
The MC9S08QE4CTGR implements the HCS08 CPU core with BGND instruction support and handles up to 32 interrupt/reset sources. Its internal clock source (ICS) uses a frequency-locked loop (FLL) trimmed to ±0.2% resolution, enabling stable bus frequencies from 1 MHz to 10 MHz across voltage and temperature.
Power management includes Stop2 and Stop3 modes with sub-µA quiescent current, a dedicated 1 kHz low-power oscillator for RTC wake-up, and peripheral clock gating to disable unused modules. The ADC operates down to 1.8 V with 2.5 µs conversion time and includes a 1.7 mV/°C temperature sensor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | HCS08 8-bit core with BGND instruction and 32 interrupt/reset vectors |
| Flash / RAM | 4096 bytes flash (read/program/erase over full voltage/temp); 256 bytes RAM |
| Operating Voltage | 1.8 V to 3.6 V - enables direct Li-ion battery or 2xAA supply operation without regulator |
| Max Clock Speed | 20 MHz at 3.6 V, -40°C to +85°C - supports real-time control loops with <50 ns instruction cycle |
| ADC | 12-bit, 10-channel, 2.5 µs conversion - includes internal bandgap reference and temperature sensor |
| Low-Power Modes | Stop3 mode draws 0.4–6 µA; 6 µs wake-up time - suitable for battery-powered wake-on-event systems |
| I/O Pins | 26 GPIOs + 1 output-only + 1 input-only; configurable pull-ups, slew rate, and drive strength |
Pinout & Package
MC9S08QE4CTGR is housed in a 32-pin QFN package (case number 2078-01, copper-wire bonded per QFN_Addendum Rev. 0), with 5 mm × 5 mm footprint, 0.5 mm pitch, and exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Core power supply | Primary 1.8–3.6 V supply for digital logic and I/O; decoupling required near pin |
| VSS | Digital ground | Reference return path for all digital circuitry; must be connected to PCB ground plane |
| VDDA/VREFH | Analog power / ADC reference high | Separate analog supply pin; ties to VDD by default but may be isolated for noise-sensitive ADC use |
| VSSA/VREFL | Analog ground / ADC reference low | Independent analog ground; recommended to route separately from digital ground and tie at single point |
| PTA5/IRQ/TCLK/RESET | Multi-function pin | Configurable as active-low reset input (open-drain with internal pull-up) or IRQ/TCLK signal |
| PTA4/ACMP1O/BKGD/MS | Debug & analog output | Single-wire background debug (BKGD) interface; also outputs ACMP1 comparator result |
| PTB0–PTB7 | Port B I/O | Includes RxD/TxD (SCI), MOSI/MISO/SPSCK (SPI), SDA/SCL (I²C), TPM channels, and KBI inputs |
| PTC0–PTC7 | Port C I/O | Hosts ACMP2 inputs/outputs, TPM2CH2, and general-purpose digital I/O with hysteresis |
| PTD0–PTD3 | Port D I/O | Four general-purpose pins with configurable pull-up/pull-down and drive strength |
Key Features
| Feature | Design Value |
|---|---|
| Single-wire background debug (BDC) | Enables in-circuit programming and debugging using only BKGD pin - reduces test fixture complexity |
| Flash block protection | Prevents unauthorized read/write access to flash and RAM - meets basic firmware security requirements |
| Low-voltage detection (LVD) | Configurable reset or interrupt at 1.80–1.96 V threshold - protects against brown-out data corruption |
| Real-time counter (RTC) | 8-bit modulus counter with binary/decimal prescaler; runs on 1 kHz LPO in all modes - enables calendar/time-of-day without external crystal |
| Peripheral clock gating | Software-controlled register disables clocks to idle modules - reduces dynamic current by >30% in partial-active states |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08QG8CDTE | 1 KB flash, 128 B RAM, 8-pin SOIC - lacks ADC, RTC, and I²C; no BKGD debug | Suitable only for simple GPIO/state-machine tasks; not viable for sensor acquisition or communication | Select only if design requires minimal footprint and zero analog/peripheral needs |
| S9KEAZ128AMLH | ARM Cortex-M0+, 128 KB flash, 16 KB RAM, 48 MHz - higher performance, larger memory, different toolchain | Requires migration from HCS08 assembly/C to ARM GCC/Keil; supports USB, CAN, more advanced peripherals | Choose for future-proofing or when scaling beyond 4 KB flash; not drop-in compatible |
Compared with MC9S08QE4CTGR, MC9S08QG8CDTE sacrifices all analog and communication capability for size reduction, while S9KEAZ128AMLH offers architectural upgrade at cost of software rework and higher BOM cost - making MC9S08QE4CTGR optimal for legacy-compatible, mixed-signal 8-bit control.

FAQ
What is the maximum operating frequency of the MC9S08QE4CTGR?
The MC9S08QE4CTGR supports up to 20 MHz CPU operation at 3.6 V across the full –40°C to +85°C temperature range. At lower supply voltages (e.g., 1.8 V), the maximum safe frequency is reduced per the internal FLL lock range and voltage-dependent timing margins specified in the datasheet's AC characteristics section.
Does the MC9S08QE4CTGR include an integrated temperature sensor?
Yes, the MC9S08QE4CTGR integrates a calibrated 1.7 mV/°C temperature sensor accessible via the ADC's dedicated channel. This sensor operates across the full –40°C to +85°C range and functions in Stop3 mode, enabling accurate thermal monitoring without external components.
What debug interface does the MC9S08QE4CTGR support?
The MC9S08QE4CTGR supports a single-wire background debug (BKGD) interface on PTA4, enabling in-circuit programming, breakpoint setting, and real-time register inspection using standard Freescale/NXP BDM tools - no JTAG header or additional pins required.
Can the MC9S08QE4CTGR operate from a 2-cell alkaline battery?
Yes, the MC9S08QE4CTGR operates from 1.8 V to 3.6 V, matching the discharge curve of two alkaline AA/AAA cells (3.2 V fresh → ~1.9 V end-of-life). Its low-voltage detection (LVD) circuit triggers reset below 1.80 V, preventing unreliable operation during battery depletion.
Is the MC9S08QE4CTGR pin-compatible with other QE-series MCUs?
No - the MC9S08QE4CTGR shares the same 32-pin QFN package and core peripheral set with MC9S08QE8, but differs in flash/RAM size and some pin multiplexing defaults. Pin assignments match the QE8 family in 32-pin variants, but software initialization must account for memory map and module enable differences.
