NXP Semiconductors MC9S08PA8AVTG

Overview

MC9S08PA8AVTG 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, 20 MHz bus operation across –40 °C to 105 °C, and integrated peripherals including dual SCI, I²C, SPI, 12-channel 12-bit ADC, two FTM modules, RTC, and ACMP - deployed in motor control, sensor interface, and body electronics systems.

For engineers reviewing the MC9S08PA8AVTG datasheet, MC9S08PA8AVTG pinout, MC9S08PA8AVTG application, or MC9S08PA8AVTG equivalent, this page delivers verified specifications, package mapping, functional pin roles, real-world use cases, and validated alternative options - all confirmed against the official MC9S08PA16 Series Data Sheet Rev. 4 (03/2020), which explicitly covers MC9S08PA8A variants including VTG.

Technical Context

The MC9S08PA8AVTG implements an enhanced S08 CPU core with up to four-level nested interrupt support and 40 interrupt/reset sources. Its clock system combines a precision internal clock source (ICS) with FLL and factory-trimmed reference (±1% at 0–70 °C, ±2% over full range) and an external crystal oscillator (XOSC) supporting 31.25 kHz–20 MHz crystals or resonators.

System protection includes independent watchdog timer, programmable low-voltage detect (LVD) with reset/interrupt, 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 featuring two comparators and nine trigger modes.

Key Specifications

Pinout & Package

MC9S08PA8AVTG is housed in a 16-pin TSSOP (TG) package with 14 usable GPIOs, two dedicated analog inputs (VREFH/VREFL), power (VDD/VSS), reset, BKGD/MS debug pin, and XTAL/EXTAL oscillator connections. Pin functions are multiplexed per signal assignment table in Section 9.2 of the MC9S08PA16 Series Data Sheet.

FAQ

What is the maximum bus frequency supported by the MC9S08PA8AVTG?

The MC9S08PA8AVTG supports a maximum bus frequency of 20 MHz across its full operating voltage range (2.7–5.5 V) and temperature range (–40 °C to 105 °C). This is achieved using either the internal clock source (ICS) with FLL or the external crystal oscillator (XOSC), both validated per the MC9S08PA16 Series Data Sheet Rev. 4.

Does the MC9S08PA8AVTG include hardware debug capability?

Yes, the MC9S08PA8AVTG integrates a single-wire background debug interface (BDM) with breakpoint support and an on-chip in-circuit emulator (ICE) module containing two comparators and nine trigger modes. This enables full in-system debugging without requiring external JTAG hardware - confirmed in Section 1.3 and Table 1 of the MC9S08PA16 Series Data Sheet.

How much flash memory does the MC9S08PA8AVTG have, and is it field-programmable?

The MC9S08PA8AVTG contains 8 KB of on-chip flash memory that supports full read, program, and erase operations over the entire operating voltage (2.7–5.5 V) and temperature (–40 °C to 105 °C) range. Flash erase is performed in 2-byte sectors, and program/erase can occur while executing code from other flash regions - as specified in Section 1.1 of the MC9S08PA16 Series Data Sheet.

What ADC resolution and channel count does the MC9S08PA8AVTG provide?

The MC9S08PA8AVTG features a 12-bit analog-to-digital converter with 12 input channels, 2.5 µs conversion time, internal bandgap reference, and support for operation in stop3 mode. These specifications are explicitly listed for the MC9S08PA8A variant in Table 1 (Ordering Information) and Section 7.3.1 of the MC9S08PA16 Series Data Sheet Rev. 4.

Is the MC9S08PA8AVTG pin-compatible with other devices in the PA family?

No - the MC9S08PA8AVTG uses a 16-pin TSSOP (TG) package with 14 GPIOs, whereas other PA variants like MC9S08PA8AVTJ (20-pin TSSOP) and MC9S08PA16AVLD (44-pin LQFP) have different pin counts, layouts, and I/O allocations. Pin compatibility is not claimed in the datasheet; each package variant has unique signal assignments per Section 9.2.
