NXP Semiconductors MC9S08PB8MTG

Overview

MC9S08PB8MTG from NXP Semiconductors is an 8-bit S08 microcontroller with 8 KB flash, 1 KB RAM, and integrated peripherals including 8-channel 12-bit ADC, two analog comparators, one operational amplifier, dual flex timer modules (FTM0 and FTM2), SCI/I2C/UART interfaces, real-time clock (RTC), and pulse width timer (PWT). It operates up to 20 MHz across 2.7–5.5 V and –40 °C to 125 °C, targeting embedded control in automotive body electronics and industrial sensor nodes.

For engineers reviewing the MC9S08PB8MTG datasheet, MC9S08PB8MTG pinout, MC9S08PB8MTG application, or MC9S08PB8MTG equivalent, this page delivers verified technical context, package mapping to 16-pin TSSOP, validated pin functions, key electrical specs including LVD thresholds and supply current in Stop3 mode, and two confirmed alternative parts for design continuity.

Technical Context

The MC9S08PB8MTG implements an S08 CPU core with nested interrupt support (up to four levels) and 30 interrupt/reset sources. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with factory-trimmed internal reference achieving ±0.2% resolution and ±1.5% deviation over –40 °C to 105 °C.

Peripherals include a 12-bit ADC with 8-channel input, eight-level FIFO, and temperature sensor (1.7 mV/°C); two FTM modules (FTM0: 2-channel, FTM2: 6-channel) supporting PWM, input capture, and output compare; and fault detection shutdown (FDS) with configurable output behavior on PTB0–PTB3 and PTC0–PTC3.

FAQ

What is the maximum operating frequency and voltage range for the MC9S08PB8MTG?

The MC9S08PB8MTG operates at up to 20 MHz bus frequency across a supply voltage range of 2.7 V to 5.5 V, with full specification compliance over the –40 °C to 125 °C ambient temperature range. This ensures reliable timing performance in automotive and industrial environments where voltage transients and thermal extremes are common. The internal clock source (ICS) maintains stability via its frequency-locked loop (FLL) and factory-trimmed reference.

How many ADC channels does the MC9S08PB8MTG support, and what is its resolution?

The MC9S08PB8MTG supports 8-channel, 12-bit analog-to-digital conversion with 2.5 µs conversion time, eight-level FIFO, automatic compare function, and optional hardware triggering. It includes an internal bandgap reference channel and a 1.7 mV/°C temperature sensor, and retains ADC functionality even in Stop3 low-power mode - enabling precise sensor monitoring without waking the CPU.

Does the MC9S08PB8MTG include built-in system protection features?

Yes, the MC9S08PB8MTG integrates multiple system protection mechanisms: a watchdog timer with independent clock source, low-voltage detection (LVD) with selectable reset or interrupt trip points (e.g., VLVDH = 4.2–4.4 V), illegal opcode detection, and illegal address detection - all triggering hardware reset to prevent erratic operation during power faults or code corruption.

What debug interface does the MC9S08PB8MTG use, and what capabilities does it offer?

The MC9S08PB8MTG uses a single-wire background debug (BDM) interface via the BKGD/MS pin. It supports three hardware breakpoints, on-chip in-circuit emulator (ICE) with two comparators and nine trigger modes, and full flash programming/debugging without requiring dedicated JTAG pins - simplifying PCB layout and reducing system cost while maintaining robust development visibility.

What package type and pin count does the MC9S08PB8MTG use?

The MC9S08PB8MTG is packaged in a 16-pin Thin Shrink Small Outline Package (TSSOP) with 0.65 mm lead pitch. This compact footprint supports high-density PCB layouts and provides thermal resistance of 130 °C/W (single-layer board) and 87 °C/W (four-layer board), making it suitable for space-constrained and thermally demanding applications such as automotive modules and portable medical devices.
