Product details
Overview
MC9S08PB16VTG from NXP Semiconductors is an 8-bit S08 core microcontroller with 16 KB flash, 1 KB RAM, and operation up to 20 MHz across 2.7–5.5 V supply and –40 °C to +105 °C temperature range. It integrates a 12-channel 12-bit ADC (2.5 µs conversion), dual analog comparators, one operational amplifier (x20 fixed gain), two flex timer modules (FTM0 and FTM2), SCI/I²C/UART/LIN interfaces, RTC, CRC, and fault detection shutdown (FDS). It serves in industrial sensor nodes and motor control subsystems requiring deterministic real-time response and mixed-signal integration.
For engineers reviewing the MC9S08PB16VTG datasheet, MC9S08PB16VTG pinout, MC9S08PB16VTG application, or MC9S08PB16VTG equivalent, this page delivers verified technical context, validated package mapping, confirmed peripheral timing behavior, and precise alternative part comparisons - all grounded in NXP's Rev. 2.1 (11/2019) official datasheet and orderable part number specifications.
Technical Context
The MC9S08PB16VTG implements an S08 CPU core with four-level nested interrupt support and up to 30 interrupt/reset sources. Its clock system combines an internal frequency-locked-loop (ICS) with ±1% accuracy over 0–70 °C and ±1.5% over –40–105 °C, plus an external crystal oscillator supporting 4–20 MHz crystals.
Peripherals include two independent FTM modules (FTM0: 2-channel; FTM2: 6-channel), each configurable for input capture, output compare, or edge-/center-aligned PWM; a 12-bit ADC with FIFO, hardware trigger, and on-chip temperature sensor (1.7 mV/°C); and integrated system protection including watchdog with independent clock, low-voltage detect with programmable trip points, and illegal opcode/address reset.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | 8-bit S08 CPU with four-level nested interrupt and up to 30 interrupt sources - enables deterministic real-time task scheduling in resource-constrained embedded systems. |
| Flash / RAM | 16 KB flash (read/program/erase over full voltage/temperature range) and 1 KB RAM - supports firmware updates in field and local data buffering without external memory. |
| ADC | 12-channel, 12-bit resolution, 2.5 µs conversion time with FIFO and hardware trigger - suitable for high-speed sensor sampling in closed-loop control applications. |

Key Features
| Feature | Design Value |
|---|---|
| On-chip ICE debug module | Two comparators and nine trigger modes enable precise breakpoint-based analysis of real-time code execution without halting system clocks. |
| Fault Detection & Shutdown (FDS) | Configurable fault sources (e.g., comparator outputs) can force up to eight output pins into high-impedance, logic 0, or logic 1 states - critical for fail-safe motor driver or power stage control. |
| Low-power stop3 mode | Consumes only 1.2–1.3 µA with 1 kHz LPO clock active - supports battery-powered wake-on-event applications with sub-microamp quiescent current. |
| Bandgap-referenced ADC | Internal 1.16 V ±20 mV buffered bandgap reference ensures stable ADC conversions across voltage and temperature variations - improves measurement repeatability in unregulated supplies. |
| Hardware-triggered ADC | Accepts triggers from FTM, SCI, or PWT modules - enables synchronized sampling of motor current at precise commutation angles or UART frame boundaries. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9KEAZ128AMLH | ARM Cortex-M0+ core, 128 KB flash, 16 KB RAM, higher performance but no FDS or true open-drain pin | Requires software-based fault handling; lacks hardware FDS output state control and PTB0 open-drain capability | Select when migrating to ARM ecosystem and needing >20 MHz throughput; avoid if hardware-level fault shutdown is mandatory. |
| MC9S08AC128CFGE | S08 core, 128 KB flash, 8 KB RAM, 44-pin LQFP, includes CAN 2.0B but no OPAMP or FDS | Supports automotive CAN networks but omits analog front-end features (OPAMP, FDS, PWT) integral to MC9S08PB16VTG | Choose for CAN-based body electronics; reject for analog-intensive motor/sensor roles where MC9S08PB16VTG's integrated signal chain is essential. |
Compared with S9KEAZ128AMLH and MC9S08AC128CFGE, the MC9S08PB16VTG uniquely balances analog integration (OPAMP, ACMP, FDS), ultra-low-power stop3 mode (<1.3 µA), and hardware fault response - making it irreplaceable in cost-sensitive, safety-aware embedded systems where mixed-signal precision and deterministic shutdown are non-negotiable.

FAQ
What is the maximum operating frequency of the MC9S08PB16VTG?
The MC9S08PB16VTG 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), as specified in Table 7 of the official datasheet Rev. 2.1. This frequency is achievable using either the internal ICS clock source or an external crystal oscillator.
Does the MC9S08PB16VTG support hardware fault shutdown?
Yes, the MC9S08PB16VTG includes a Fault Detection & Shutdown (FDS) module that can monitor up to eight configurable fault sources (e.g., analog comparator outputs) and drive designated output pins into high-impedance, logic 0, or logic 1 states - enabling hardware-level protection of external power stages without CPU intervention.
What analog peripherals are integrated into the MC9S08PB16VTG?
The MC9S08PB16VTG integrates a 12-channel 12-bit ADC with 2.5 µs conversion time and FIFO, two analog comparators (ACMP0/ACMP1) with selectable DAC reference, one operational amplifier (OPAMP) with fixed x20 gain, and an on-chip temperature sensor (1.7 mV/°C) - all accessible through shared pin multiplexing and operable in stop3 mode.
Is the MC9S08PB16VTG pin-compatible with other members of the PB family?
No - the MC9S08PB16VTG uses a 16-pin TSSOP package (TG suffix), while MC9S08PB16VTJ uses a 20-pin TSSOP. Pin assignments differ between packages, and functional pin mapping (e.g., FTM2 channels, FDS outputs) is not identical across variants; PCB layout must be verified per specific orderable part number.
What debug interface does the MC9S08PB16VTG provide?
The MC9S08PB16VTG features a single-wire background debug (BKGD/MS) interface compliant with NXP's BDM specification, supporting three hardware breakpoints, on-chip in-circuit emulator (ICE) with two comparators and nine trigger modes, and full flash programming - all using only one dedicated pin.
