Product details
Overview
MC9S08PA8VLD from NXP Semiconductors is an 8-bit S08 microcontroller designed for cost-sensitive industrial and automotive control applications. It features 8 KB flash, 2 KB RAM, 256 B EEPROM, 12-bit ADC (12-channel), dual SCI/LIN interfaces, and operates at up to 20 MHz bus frequency across –40 °C to 105 °C. Its integrated FTM modules, real-time clock, and low-power stop mode support motor control and sensor interface functions.
For engineers reviewing the MC9S08PA8VLD datasheet, MC9S08PA8VLD pinout, MC9S08PA8VLD application, or MC9S08PA8VLD equivalent, this page delivers verified technical context, package mapping, peripheral timing behavior, supply current profiles in Run/Wait/Stop3 modes, and validated alternative options for embedded control design.
Technical Context
The MC9S08PA8VLD implements an enhanced S08 CPU core with four-level nested interrupt support and up to 40 interrupt/reset sources. Its clock system combines a Pierce oscillator (XOSC) for external crystal/resonator operation (4–20 MHz or 31.25–39.0625 kHz) and an internal clock source (ICS) with frequency-locked-loop (FLL) and factory-trimmed reference enabling ±1% accuracy from 0 °C to 70 °C.
System protection includes independent watchdog timer, programmable low-voltage detect (LVD) with four warning levels and hysteresis, illegal opcode/address detection, and flash/RAM access protection. Debug is enabled via single-wire background debug interface (BDM) with three breakpoints and on-chip ICE module supporting nine trigger modes.

The MC9S08PA8VLD 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 is achieved using either the internal clock source (ICS) with FLL or an external crystal/resonator via the XOSC module, as confirmed in Table 1 and Section 6.2.1 of the MC9S08PA16 Series Data Sheet Rev. 4.
Does the MC9S08PA8VLD include hardware support for LIN communication?
Yes, the MC9S08PA8VLD includes two serial communication interface (SCI) modules with explicit LIN extension support, as documented in the "Peripherals" section of the datasheet. Each SCI supports 13-bit break detection, automatic sync field handling, and checksum generation - meeting ISO 17987-4 requirements for LIN slave node implementation without external transceivers.
What are the memory resources available on the MC9S08PA8VLD?
The MC9S08PA8VLD integrates 8 KB of on-chip flash memory (with 100,000 program/erase cycles), 2 KB of RAM, and 256 bytes of EEPROM organized in 2-byte erase sectors. All memory blocks support read/program/erase over the full operating voltage and temperature range, and flash supports program/erase while executing code from other flash regions.
How many analog-to-digital converter channels does the MC9S08PA8VLD support?
The MC9S08PA8VLD supports 12 analog input channels for its 12-bit ADC, as specified in Table 1 (Ordering Information) and Section 7.3.1 of the datasheet. The ADC delivers 2.5 µs conversion time, includes data buffers with optional watermark interrupt, and operates in Stop3 mode when configured with ADLPC = 1.
Is the MC9S08PA8VLD pin-compatible with the MC9S08PA16VLD?
Yes, the MC9S08PA8VLD is fully pin-compatible with the MC9S08PA16VLD in the 44-pin LQFP package (VLD suffix), sharing identical pin assignments, signal multiplexing, and peripheral mapping per Figure 1 and Section 9.2 of the MC9S08PA16 Series Data Sheet Rev. 4. This enables drop-in replacement where flash size suffices.
