NXP Semiconductors MC9S08PA8AVTGR

Overview

MC9S08PA8AVTGR 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 SCI/LIN-capable UARTs. It operates at up to 20 MHz bus frequency across –40 °C to 105 °C and supports stop3 low-power mode with <1.4 µA typical current.

For engineers reviewing the MC9S08PA8AVTGR datasheet, MC9S08PA8AVTGR pinout, MC9S08PA8AVTGR application, or MC9S08PA8AVTGR equivalent, key selection factors include its 16-TSSOP package, 14 GPIO count, integrated RTC and CRC module, ultra-high-current sink pins (20 mA), and single-wire background debug interface for in-circuit development.

Technical Context

The MC9S08PA8AVTGR implements an S08 CPU core with four-level nested interrupt support and up to 40 interrupt/reset sources. Its clock system combines a precision internal clock source (ICS) with FLL and factory-trimmed reference (±1% over 0–70 °C), plus external crystal oscillator support (4–20 MHz).

System protection includes independent watchdog timer, programmable low-voltage detect (LVD) with four warning thresholds, illegal opcode/address detection, and flash/RAM access protection. Peripheral integration covers two FTM modules (6+2 channels), I²C, SPI, two SCI interfaces with LIN extension, and analog comparator with filtering.

FAQ

What is the maximum operating frequency of the MC9S08PA8AVTGR?

The MC9S08PA8AVTGR 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 frequency is achieved using either the internal clock source (ICS) with FLL or an external crystal oscillator (4–20 MHz), and is validated per the device's electrical specifications in the official NXP datasheet Rev. 4 (03/2020).

Does the MC9S08PA8AVTGR support LIN communication natively?

Yes, the MC9S08PA8AVTGR supports LIN 2.0 physical layer natively through its two SCI modules, which include hardware features such as 13-bit break detection, sync field handling, and checksum generation. This enables direct implementation of LIN slave nodes without external transceivers - confirmed in Section 7.4.2 of the MC9S08PA16 Series Data Sheet, which explicitly covers MC9S08PA8A devices.

How much current does the MC9S08PA8AVTGR draw in its lowest power mode?

In Stop3 mode with only the 1 kHz LPO clock active, the MC9S08PA8AVTGR draws a typical supply current of 1.35 µA at 5 V and 1.3 µA at 3 V, as specified in Table 5 of the datasheet. Additional peripherals like the ADC or LVD can increase this by up to 40 µA or 128 µA respectively, but the base stop3 current remains among the lowest in its class for 8-bit MCUs with integrated RTC and debug interface.

What package type is used for the MC9S08PA8AVTGR?

The MC9S08PA8AVTGR uses a 16-pin TSSOP package (designator TG), measuring 3.0 × 4.4 mm with 0.65 mm lead pitch. This compact, surface-mount package is optimized for space-constrained applications and features a thermal pad for improved heat dissipation - confirmed in Table 1 (Ordering Information) and Section 8 (Dimensions) of the MC9S08PA16 Series Data Sheet.

Can the MC9S08PA8AVTGR perform ADC conversions while in stop mode?

Yes, the MC9S08PA8AVTGR supports ADC operation in Stop3 mode, enabling low-power sensor polling without waking the CPU. The ADC module retains full functionality including hardware triggers, data buffering, and automatic compare - as documented in Section 7.3.1 and Table 5 (Supply Current Characteristics), where "ADC adder to stop3" specifies +40 µA typical current increase during conversion.
