Product details
Overview
MC9S08QD2CPC from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 2048 bytes of flash, 128 bytes of RAM, and a 16 MHz CPU core. It integrates ADC, two timer/PWM modules (TIM1 and TIM2), keyboard interrupt, and internal clock source with FLL. It targets low-cost embedded control in space-constrained industrial and consumer devices.
For engineers reviewing the MC9S08QD2CPC datasheet, MC9S08QD2CPC pinout, MC9S08QD2CPC application, or MC9S08QD2CPC equivalent, key selection criteria include flash/RAM size, 8-pin SOIC/PDIP package compatibility, single-wire BDM debug support, and integrated analog-peripheral resource count for minimal-BOM designs.
Technical Context
The MC9S08QD2CPC implements the HCS08 CPUV2 core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources and background debugging with one hardware breakpoint. Its ICS module delivers system clock via FLL locked to an internal reference trimmed to ±0.2% resolution.
Peripherals include a 4-channel 10-bit ADC with temperature sensor and bandgap reference, two independent timer/PWM units (TIM1: 2-channel; TIM2: 1-channel), and a 4-pin keyboard interrupt module with software-selectable edge/level sensitivity and internal pullups.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08QD4CPC | 4 kB flash, 256 B RAM - double memory capacity; otherwise identical peripheral set and pinout | Suitable where firmware complexity or data logging requires >2 kB code space | Select MC9S08QD4CPC when future firmware expansion or bootloader+application partitioning is needed |
| S9S08QD2CTG | Same core/peripherals but automotive-grade (-40°C to 125°C), TSSOP-16 package, and different reset behavior under LVD | Required for AEC-Q100-compliant automotive body electronics | Choose S9S08QD2CTG only for automotive environments needing extended temperature and qualification |
Compared with MC9S08QD2CPC, MC9S08QD4CPC offers scalable memory within identical footprint and debug interface, while S9S08QD2CTG trades package and qualification for broader environmental robustness - neither is pin-compatible due to differing pin counts and thermal specs.

FAQ
What is the maximum operating frequency of the MC9S08QD2CPC?
The MC9S08QD2CPC features an HCS08 CPU core rated for up to 16 MHz operation. This frequency is achieved using the internal clock source (ICS) with its frequency-locked loop (FLL), which locks to a precision-trimmed internal reference. The 16 MHz bus speed supports real-time response in control loops and communication timing without requiring external oscillators.
Does the MC9S08QD2CPC support in-circuit debugging?
Yes, the MC9S08QD2CPC supports single-wire background debug (BDM) via the BKGD/MS pin. It provides breakpoint capability with one hardware breakpoint active during in-circuit debugging, plus two additional breakpoints managed by the on-chip debug module. This enables full firmware inspection, register access, and flash programming without requiring dedicated debug headers or JTAG adapters.
What are the power supply requirements for the MC9S08QD2CPC?
The MC9S08QD2CPC operates from a single supply rail of 2.7 V to 5.5 V over the full industrial temperature range (–40°C to +85°C). It includes low-voltage detection with configurable reset or interrupt behavior, and supports multiple low-power modes - Wait, Stop1, Stop2, and Stop3 - enabling current draw as low as 1 µA in deep stop states.
How many I/O pins does the MC9S08QD2CPC have, and what are their capabilities?
The MC9S08QD2CPC provides six I/O terminals: four general-purpose bidirectional pins (PTA0–PTA3), one input-only pin (PTA4), and one output-only pin (PTA5). All I/Os support software-selectable pullups when used as inputs, and slew rate/drive strength control when used as outputs. Internal pullups on RESET and IRQ further reduce external component count.
Is the MC9S08QD2CPC pin-compatible with other members of the QD series?
The MC9S08QD2CPC shares identical pin assignments and electrical characteristics with MC9S08QD4CPC in both 8-pin PDIP and SOIC packages. However, it is not pin-compatible with S9S08QD2CTG (16-pin TSSOP) or any QD-series variant in larger packages. Pin compatibility is strictly limited to same-package variants within the MC9S08QDx family.
