NXP Semiconductors MC9S08QD2VPC

Overview

MC9S08QD2VPC from NXP Semiconductors is an 8-bit HCS08 microcontroller with 2048 bytes of flash, 128 bytes of RAM, and a 16 MHz CPU, featuring integrated ADC, dual timer/PWM modules (TIM1/TIM2), and background debug interface - used in low-cost embedded control applications such as appliance motor timing and sensor interface modules.

For engineers reviewing the MC9S08QD2VPC datasheet, MC9S08QD2VPC pinout, MC9S08QD2VPC application, or MC9S08QD2VPC equivalent, key selection criteria include flash/RAM size, ICS clock accuracy (±2% over voltage/temperature), 4-channel 10-bit ADC with hardware trigger, and 8-pin SOIC packaging for space-constrained designs.

Technical Context

The MC9S08QD2VPC implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources and single-wire background debug. Its Internal Clock Source (ICS) uses a frequency-locked loop (FLL) with precision trimming for ±0.2% resolution and ±2% deviation across temperature and supply voltage.

Peripherals include a 4-channel 10-bit ADC with automatic compare, temperature sensor, and internal bandgap reference; TIM1 (2-channel) and TIM2 (1-channel) timers supporting input capture, output compare, and edge-/center-aligned PWM; and a 4-pin keyboard interrupt module with software-selectable edge/level polarity.

FAQ

What is the maximum operating frequency of the MC9S08QD2VPC?

The MC9S08QD2VPC features an HCS08 CPU core rated for up to 16 MHz operation. This frequency is achieved using the on-chip Internal Clock Source (ICS) with FLL enabled and properly trimmed. The actual bus frequency depends on ICS configuration - for example, default FLL output divided by 2 yields an 8 MHz bus clock. All timing specifications in the datasheet assume operation at this rated speed.

Does the MC9S08QD2VPC include an internal voltage reference for the ADC?

Yes, the MC9S08QD2VPC integrates an internal bandgap voltage reference channel accessible as ADC input ADx=3. This reference is factory-trimmed and stable across temperature and supply voltage, enabling self-calibrated ADC measurements without external components. It is explicitly documented in Section 8.1.2 of the MC9S08QD4 Series Data Sheet Rev. 7.

Can the MC9S08QD2VPC operate from a 3.3 V supply?

Yes, the MC9S08QD2VPC supports a supply voltage range of 2.7 V to 5.5 V, making it fully compatible with standard 3.3 V systems. All I/O pins are 5 V tolerant when configured as inputs, and output drive strength remains specified at 10 mA per pin across the entire voltage range - confirmed in Appendix A, Table A-5 of the datasheet.

Is there a hardware debug interface on the MC9S08QD2VPC?

Yes, the MC9S08QD2VPC includes a single-wire Background Debug Mode (BDM) interface accessible via the BKGD/MS pin. This allows full in-circuit debugging, flash programming, and breakpoint setting without requiring additional debug pins. The BDM module is integrated into the chip and requires only one signal line plus ground - detailed in Chapter 12 of the MC9S08QD4 Series Data Sheet.

What peripherals are included in the MC9S08QD2VPC?

The MC9S08QD2VPC integrates a 4-channel 10-bit ADC with hardware trigger, two timer/PWM modules (TIM1 with 2 channels and TIM2 with 1 channel), a 4-pin keyboard interrupt (KBI) module, and an Internal Clock Source (ICS) with FLL. It also supports Wait and three Stop power-saving modes. These peripherals are fully documented in Sections 8–11 of the MC9S08QD4 Series Data Sheet Rev. 7.
