Product details
Overview
MC9S08PA8AVLC from NXP Semiconductors is an 8-bit S08 microcontroller designed for cost-sensitive industrial and automotive control applications, featuring 8 KB flash, 2 KB RAM, 256 B EEPROM, 12-bit ADC with 12 channels, and dual serial interfaces (SCI/UART ×2, I²C, SPI). It operates at up to 20 MHz bus frequency across –40 °C to 105 °C and supports low-power stop3 mode with peripheral clock gating.
For engineers reviewing the MC9S08PA8AVLC datasheet, MC9S08PA8AVLC pinout, MC9S08PA8AVLC application, or MC9S08PA8AVLC equivalent, this page delivers verified technical context, validated package mapping (32-pin LQFP), confirmed peripheral set (FTM ×2, ACMP, RTC, CRC), and real-world selection guidance against functionally aligned alternatives.
Technical Context
The MC9S08PA8AVLC implements an enhanced S08 CPU core with four-level nested interrupt support and up to 40 interrupt/reset sources. Its internal clock system integrates a frequency-locked loop (FLL) with factory-trimmed internal reference (±2% over –40 °C to 105 °C) and supports external crystal oscillation from 4 MHz to 20 MHz.
Peripherals include two FlexTimer Modules (one 6-channel, one 2-channel), a 12-channel 12-bit ADC with 2.5 µs conversion time and stop-mode operation, and dual SCI modules with LIN extension support. System protection includes independent watchdog, programmable low-voltage detection with four warning levels, and illegal opcode/address reset logic.

FAQ
What is the maximum operating frequency of the MC9S08PA8AVLC?
The MC9S08PA8AVLC supports a maximum bus frequency of 20 MHz across its full operating voltage range (2.7 V to 5.5 V) and temperature range (–40 °C to 105 °C). This frequency is achieved using either the internal FLL (with factory-trimmed reference) or an external crystal oscillator between 4 MHz and 20 MHz.
Does the MC9S08PA8AVLC support in-circuit debugging?
Yes, the MC9S08PA8AVLC includes a single-wire background debug interface (BKGD) on PTA4, enabling full in-circuit emulation with three hardware breakpoints and on-chip ICE debug module support. This allows real-time code execution control, register inspection, and memory access during development without requiring additional debug probes.
How much EEPROM does the MC9S08PA8AVLC have, and what is its erase granularity?
The MC9S08PA8AVLC contains 256 bytes of user EEPROM with 2-byte erase sectors. This allows fine-grained nonvolatile storage for calibration data, device configuration, or runtime parameters without erasing larger blocks-preserving other stored values during field updates.
Can the MC9S08PA8AVLC operate in low-power modes while maintaining ADC functionality?
Yes, the MC9S08PA8AVLC supports ADC operation in Stop3 mode when configured with ADLPC = 1, ADLSMP = 1, and MODE = 10B. In this configuration, the ADC draws only ~40 µA additional current (at 5 V), enabling periodic sensor sampling without waking the CPU-ideal for battery-powered monitoring applications.
What package type and pin count does the MC9S08PA8AVLC use?
The MC9S08PA8AVLC uses a 32-pin LQFP package (7 mm × 7 mm, 0.8 mm pitch) with exposed thermal pad. This package supports 28 GPIOs, including four 20 mA ultra-high-current sink pins (PTB4, PTB5, PTD0, PTD1), two true open-drain outputs (PTA2, PTA3), and one output-only debug pin (PTA4/BKGD).
