NXP Semiconductors MC9S08PB16VTJ

Overview

MC9S08PB16VTJ from NXP Semiconductors is an 8-bit S08 microcontroller with 16 KB flash, 1 KB RAM, and integrated peripherals including dual FTM modules (6-channel + 2-channel), 12-bit 12-channel ADC, I²C, SCI/UART with LIN support, two analog comparators, one operational amplifier (gain ×20), RTC, CRC, and fault detection shutdown (FDS). It operates up to 20 MHz across –40 °C to 105 °C at 2.7–5.5 V, targeting embedded control in industrial sensors and motor drives.

For engineers reviewing the MC9S08PB16VTJ datasheet, MC9S08PB16VTJ pinout, MC9S08PB16VTJ application, or MC9S08PB16VTJ equivalent, key selection criteria include its TSSOP-20 package, single-wire background debug interface, stop3 mode current of 1.3 µA, internal clock source with ±1% deviation over –40 °C to 105 °C, and true open-drain PTB0 pin for level-shifting interfaces.

Technical Context

The MC9S08PB16VTJ implements an enhanced HCS08 CPU core with four-level nested interrupt support and up to 30 interrupt/reset sources. Its internal clock source (ICS) integrates a frequency-locked loop (FLL) with factory-trimmed internal reference (0.2% resolution), enabling stable 20 MHz operation without external crystal when configured in FEI mode.

Peripherals are tightly coupled via hardware triggers: ADC supports hardware-triggered conversions from FTM, SCI, or RTC; FDS module can force PTB0 and other outputs into high-impedance on fault detection; and system interconnection logic enables autonomous event chaining (e.g., SCI RxD edge triggering FTM capture) with minimal software overhead.

FAQ

What is the maximum operating frequency and voltage range for the MC9S08PB16VTJ?

The MC9S08PB16VTJ 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. Its internal clock source (ICS) maintains ±1% accuracy across this temperature range without requiring an external crystal, enabling reliable high-speed operation in variable environmental conditions.

Does the MC9S08PB16VTJ support hardware debugging, and what interface is used?

Yes, the MC9S08PB16VTJ supports in-circuit debugging via a single-wire background debug (BKGD) interface. This interface enables full visibility into CPU registers, memory, and peripheral states, supports up to three hardware breakpoints, and integrates an on-chip ICE module with nine trigger modes for precise event capture during development and validation of the MC9S08PB16VTJ.

How does the Fault Detection Shutdown (FDS) module function on the MC9S08PB16VTJ?

The FDS module on the MC9S08PB16VTJ monitors configurable fault inputs (e.g., ACMP outputs or external signals) and forces designated output pins-including PTB0, PTA0–PTA3, and PTC0–PTC3-into high-impedance, logic 0, or logic 1 states based on register configuration. This hardware-enforced response occurs independently of CPU execution, ensuring sub-microsecond shutdown critical for motor driver protection in the MC9S08PB16VTJ.

What analog peripherals are integrated into the MC9S08PB16VTJ?

The MC9S08PB16VTJ integrates a 12-bit 12-channel ADC with 2.5 µs conversion time and 8-level FIFO, two analog comparators (ACMP0/ACMP1) with selectable 6-bit DAC reference, one operational amplifier (OPAMP) with fixed ×20 gain and 100 mV single-ended input range, and an on-chip temperature sensor (1.7 mV/°C). These enable complete analog front-end functionality without external signal conditioning components in the MC9S08PB16VTJ.

Is the MC9S08PB16VTJ compatible with LIN communication protocols?

Yes, the MC9S08PB16VTJ's SCI module includes explicit LIN extension support, enabling it to operate as a LIN slave node with automatic sync-break detection, checksum handling, and timing compliance per LIN 2.x specifications. This capability is confirmed in the official MC9S08PB16 data sheet and allows direct integration into automotive body control networks using the MC9S08PB16VTJ.
