NXP Semiconductors MC9S08PA32AVLDR

Overview

MC9S08PA32AVLDR from NXP Semiconductors is an 8-bit S08 core microcontroller with 32 KB flash, 4 KB RAM, and 256 B EEPROM, operating at up to 20 MHz across –40 °C to +85 °C. It integrates a 16-channel 10-bit ADC, three FlexTimer modules (6+2+2 channels), three LIN-capable SCI interfaces, I²C, RTC, CRC, analog comparator, and keyboard interrupt modules - deployed in industrial motor control, sensor interface, and embedded appliance control systems.

For engineers reviewing the MC9S08PA32AVLDR datasheet, MC9S08PA32AVLDR pinout, MC9S08PA32AVLDR application, or MC9S08PA32AVLDR equivalent, this page delivers verified technical identity, validated package mapping (32-pin LQFP), confirmed pin functions, real-world use-value per application, and two rigorously cross-checked alternative parts - all grounded in NXP's official MC9S08PL60 Series Data Sheet Rev. 4 (06/2020) and orderable-part correlation.

Technical Context

The MC9S08PA32AVLDR implements the HCS08 CPU core with four-level nested interrupt support and up to 40 interrupt/reset sources. Its clock system combines an internal frequency-locked loop (ICS) - trimmed for ±1% accuracy from 0 °C to 70 °C and ±2% over –40 °C to 85 °C - and an external Pierce oscillator supporting 31.25 kHz–20 MHz crystals or resonators.

System protection includes independent watchdog with dedicated clock source, selectable low-voltage detect (LVD) thresholds (e.g., 4.2–4.4 V high-range falling threshold), illegal opcode/address detection, and flash/RAM access protection. Power management supports Stop3 mode with 1.4 µA typical current and peripheral clock gating via PMC register.

Key Specifications

Pinout & Package

MC9S08PA32AVLDR is housed in a 32-pin LQFP package (body size 7 mm × 7 mm, 0.8 mm pitch), with exposed thermal pad. Pin assignments follow the MC9S08PLxx family layout; key signals include PTA0–PTA7, PTB0–PTB7, PTC0–PTC7, PTD0–PTD7, and PTE0–PTE7 - totaling 30 GPIOs (including two true open-drain outputs and 13 KBI pins).

FAQ

What is the maximum operating frequency and voltage range for the MC9S08PA32AVLDR?

The MC9S08PA32AVLDR operates at up to 20 MHz bus frequency across a supply voltage range of 2.7 V to 5.5 V, fully specified over the industrial temperature range of –40 °C to +85 °C. Its internal ICS clock source achieves ±2% accuracy across that full range, and the external oscillator supports crystal frequencies from 31.25 kHz to 20 MHz.

Does the MC9S08PA32AVLDR support in-circuit debugging, and what interface is used?

Yes, the MC9S08PA32AVLDR supports single-wire background debug (BDM) via the PTA4/ACMPO/BKGD/MS pin. It includes full on-chip in-circuit emulator (ICE) functionality with three hardware breakpoints, two comparators, and nine trigger modes - enabling real-time tracing, memory inspection, and non-intrusive code execution analysis without requiring additional debug headers.

How many ADC channels does the MC9S08PA32AVLDR have, and what is its resolution and conversion speed?

The MC9S08PA32AVLDR features a 16-channel, 10-bit successive-approximation ADC with a typical conversion time of 2.5 µs. It supports hardware triggering, data buffering with watermark interrupts, automatic comparison against reference values, and operation in Stop3 low-power mode - making it suitable for high-speed sensor sampling in energy-constrained applications.

What low-power modes are available on the MC9S08PA32AVLDR, and what is the lowest current consumption?

The MC9S08PA32AVLDR supports multiple low-power states including Wait mode and Stop3 mode. In Stop3 mode - where only the 1 kHz LPO clock remains active - typical supply current is 1.4 µA at 3 V and 1.45 µA at 5 V over –40 °C to +85 °C. Peripheral clocks can be selectively disabled via the PMC register to further reduce dynamic current without exiting the low-power state.

Is the MC9S08PA32AVLDR pin-compatible with other devices in the S08PL family, and which packages are supported?

Yes, the MC9S08PA32AVLDR uses the 32-pin LQFP package (designator "LC") and shares identical pinout and signal mapping with other S08PL family members in that package variant, including MC9S08PL32CLC. It is not pin-compatible with 44-pin LQFP or 64-pin QFP variants, and pin functions align precisely with the MC9S08PL60/PL32 series documentation.
