Product details
Overview
MC9S08PA16AVTG 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, two SCI/LIN interfaces, I²C, SPI, RTC, and analog comparator - deployed in automotive body control modules, industrial sensor nodes, and smart appliance motor controllers.
For engineers reviewing the MC9S08PA16AVTG datasheet, MC9S08PA16AVTG pinout, MC9S08PA16AVTG application, or MC9S08PA16AVTG equivalent, key selection factors include its 16-TSSOP package with 14 GPIOs, ultra-high-current sink pins (20 mA), stop3 mode current of 1.3 µA, and integrated background debug interface for in-circuit development.
Technical Context
The MC9S08PA16AVTG implements an enhanced S08 CPU core with four-level nested interrupt support and up to 40 interrupt/reset sources. Its clock system combines a 4–20 MHz external crystal oscillator (XOSC) and an internal clock source (ICS) with FLL-based frequency multiplication, enabling precise bus timing across voltage (2.7–5.5 V) and temperature ranges.
System-level protection includes independent watchdog timer, programmable low-voltage detect (LVD) with four warning thresholds, illegal opcode/address detection, and flash/RAM access control. Peripheral integration targets deterministic real-time control: FTM modules support edge- and center-aligned PWM, ADC operates in stop mode with hardware trigger, and SCI modules include LIN 2.1 extension support.

FAQ
What is the maximum operating frequency and voltage range for the MC9S08PA16AVTG?
The MC9S08PA16AVTG operates at up to 20 MHz bus frequency across a supply voltage range of 2.7 V to 5.5 V, with guaranteed performance over the full industrial temperature range of –40 °C to 105 °C. Its internal clock source (ICS) with FLL achieves ±2% accuracy across this entire range, and the external oscillator supports 4–20 MHz crystals or 31.25–39.0625 kHz ceramic resonators.
Does the MC9S08PA16AVTG support in-circuit debugging, and what interface is used?
Yes, the MC9S08PA16AVTG supports in-circuit debugging via a single-wire background debug interface using the PTA4/BKGD pin. This interface enables breakpoint setting (up to three), real-time register inspection, and flash programming without requiring additional debug headers or JTAG pins - critical for space-constrained 16-pin TSSOP layouts.
How many GPIOs does the MC9S08PA16AVTG provide in its 16-pin TSSOP package?
The MC9S08PA16AVTG provides 14 general-purpose I/O pins in its 16-pin TSSOP package. Two pins (PTA4 and PTA5) are functionally constrained - PTA4 is output-only (BKGD/ACMPO), and PTA5 serves dual roles as IRQ input and RESET. Four of the GPIOs (PTB4, PTB5, PTD0, PTD1) support 20 mA sink/source drive for direct actuator interfacing.
What low-power modes are available on the MC9S08PA16AVTG, and what is the lowest current draw?
The MC9S08PA16AVTG offers multiple low-power modes including wait mode and Stop3 mode. In Stop3 mode - where only the 1 kHz LPO clock remains active - it draws just 1.3 µA at 5 V and 1.3 µA at 3 V. Additional current adders apply for enabled peripherals: ADC adds 40 µA, LVD adds 128 µA, and RTC contributes <1 µA, all quantified in the datasheet's supply current table.
Which communication interfaces are integrated into the MC9S08PA16AVTG?
The MC9S08PA16AVTG integrates two SCI modules (LIN-capable UARTs), one I²C interface (400 kbps, SMBus/PMBus compatible), one SPI module (full-duplex or single-wire bidirectional), and a dedicated CRC module. The SCI modules support 13-bit break detection and LIN 2.1 extensions, while I²C supports 10-bit addressing and broadcast mode - enabling flexible multi-protocol sensor and actuator interfacing.
