Product details
Overview
MC9S08PA16AVTGR from NXP Semiconductors is an 8-bit S08 microcontroller with 16 KB flash, 2 KB RAM, and 256 B EEPROM, operating at up to 20 MHz across –40 °C to 105 °C. It integrates dual FlexTimer modules (6-channel + 2-channel), 12-bit 12-channel ADC, I²C, two SCI/LIN UARTs, SPI, RTC, and analog comparator - deployed in automotive body control modules and industrial sensor nodes requiring robust low-power operation.
For engineers reviewing the MC9S08PA16AVTGR datasheet, MC9S08PA16AVTGR pinout, MC9S08PA16AVTGR application, or MC9S08PA16AVTGR equivalent, key selection criteria include bus frequency stability under voltage variation (2.7–5.5 V), stop3-mode current (1.35 µA @ 5 V), 20 mA high-drive GPIO capability, and single-wire background debug interface compatibility with legacy HCS08 toolchains.
Technical Context
The MC9S08PA16AVTGR 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 (31.25 kHz–20 MHz) and an internal FLL with factory-trimmed reference enabling ±1% accuracy from 0 °C to 70 °C.
System protection includes independent watchdog clock, programmable low-voltage detect (LVD) with four warning thresholds, illegal opcode/address reset, and flash/RAM access protection. Peripheral clock gating via SIM allows selective module disablement to reduce active current in wait/stop modes.

FAQ
What is the maximum operating frequency and voltage range for the MC9S08PA16AVTGR?
The MC9S08PA16AVTGR 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 105 °C. This voltage/frequency envelope is guaranteed by production testing (P-class) and applies to all core and peripheral functions including flash execution and ADC conversion.
Does the MC9S08PA16AVTGR support in-system programming and debugging?
Yes, the MC9S08PA16AVTGR features a single-wire background debug interface (BKGD) on PTA4, enabling full in-circuit debugging with three hardware breakpoints, on-chip ICE trace, and flash programming without removing the device from the target board. The MC9S08PA16AVTGR also supports program/erase while executing from flash memory.
How many analog-to-digital converter (ADC) channels does the MC9S08PA16AVTGR provide, and what is its resolution?
The MC9S08PA16AVTGR includes a 12-bit successive-approximation ADC with 12 input channels (ADP0–ADP11), capable of 2.5 µs conversion time. It supports operation in stop3 mode, optional hardware triggering, internal bandgap reference, and data buffer watermarking - all confirmed in Section 7.3.1 of the Rev. 4 datasheet.
What low-power modes are available on the MC9S08PA16AVTGR, and what is the lowest achievable current draw?
The MC9S08PA16AVTGR offers multiple low-power states including wait mode and stop3 mode. In stop3 mode with only the 1 kHz LPO clock active, the device draws 1.35 µA typical current at 5 V (Table 5, item 6), verified across temperature and voltage. Peripheral clocks can be selectively disabled via the SIM module to further reduce active-mode current.
Which GPIO pins on the MC9S08PA16AVTGR support 20 mA drive strength, and how are they identified?
Four GPIO pins on the MC9S08PA16AVTGR - PTB4, PTB5, PTD0, and PTD1 - support ultra-high current drive of 20 mA sink/source, as specified in Section 2 (Ordering Information) and Table 3 (DC Characteristics). These pins are explicitly designated in the datasheet and enable direct interfacing with LEDs, relays, or small actuators without external drivers.
