NXP Semiconductors MC9S08PA8VTGR

Overview

MC9S08PA8VTGR from NXP Semiconductors is an 8-bit S08 microcontroller with 8 KB flash, 2 KB RAM, and 256 B EEPROM, operating at up to 20 MHz across –40 °C to 105 °C. It integrates a 12-channel 12-bit ADC, two FTM modules (6+2 channels), dual SCI/LIN interfaces, I²C, SPI, RTC, and analog comparator - deployed in automotive body control modules and industrial sensor nodes requiring robust low-power operation.

For engineers reviewing the MC9S08PA8VTGR datasheet, MC9S08PA8VTGR pinout, MC9S08PA8VTGR application, or MC9S08PA8VTGR equivalent, this page delivers verified electrical specs, validated package mapping (16-pin TSSOP), confirmed peripheral configuration, and real-world design context for embedded control selection.

Technical Context

The MC9S08PA8VTGR implements an S08 CPU core with nested interrupt support (up to four levels) and on-chip ICE debug module featuring two comparators and nine trigger modes. Its clock system combines an internal FLL (±1% over 0–70 °C) and external crystal oscillator (4–20 MHz), enabling precise bus timing under varying supply (2.7–5.5 V) and temperature conditions.

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. Power management supports Stop3 mode with <1.35 µA typical current and peripheral clock gating to minimize active power draw.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the MC9S08PA8VTGR?

The MC9S08PA8VTGR 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 FLL (with ±1% accuracy over 0–70 °C) or an external crystal oscillator (4–20 MHz range), as specified in the MC9S08PA16 Series Data Sheet Rev. 4.

Does the MC9S08PA8VTGR support in-circuit debugging?

Yes, the MC9S08PA8VTGR includes a single-wire background debug interface (BDM) with full ICE functionality. It supports three hardware breakpoints, real-time trace via the DBG module, and on-chip emulation - all accessible through standard NXP BDM tools and compatible IDEs such as S32 Design Studio for S08.

What are the key differences between MC9S08PA8VTGR and MC9S08PA16VTGR?

The MC9S08PA8VTGR and MC9S08PA16VTGR share identical peripherals, pinout, package (16-pin TSSOP), and operating specifications - differing only in flash capacity (8 KB vs. 16 KB) and EEPROM/ADC channel count in some variants. Both are V-grade (–40 °C to +105 °C) and fully software-compatible within the S08 family toolchain.

Can the MC9S08PA8VTGR operate in low-power modes while maintaining RTC functionality?

Yes, the MC9S08PA8VTGR supports Stop3 mode with the 1 kHz low-power oscillator (LPO) active, allowing the 16-bit RTC to continue counting and generate wake-up interrupts. Typical Stop3 current is 1.35 µA at 5 V, and RTC operation adds less than 1 µA - confirmed in Table 5 of the MC9S08PA16 Series Data Sheet Rev. 4.

Which pins on the MC9S08PA8VTGR support 20 mA drive strength?

The MC9S08PA8VTGR has four ultra-high-current sink/source pins: PTB4, PTB5, PTD0, and PTD1. Each delivers ±20 mA at 5 V (or ±10 mA at 3 V) with VOL ≤ 0.8 V and VOH ≥ VDD – 0.8 V, enabling direct driving of LEDs, relays, or small solenoids without external drivers - as characterized in Table 3 of the official datasheet.
