NXP Semiconductors MC9S08PB8VTG

Overview

MC9S08PB8VTG from NXP Semiconductors is an 8-bit S08 core microcontroller with 8 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), two analog comparators, one fixed-gain ×20 opamp, dual flex timer modules (FTM0 and FTM2), SCI/I²C/UART/LIN interfaces, real-time clock, CRC engine, and fault detection shutdown (FDS) - deployed in industrial sensor nodes and motor control subsystems.

For engineers reviewing the MC9S08PB8VTG datasheet, MC9S08PB8VTG pinout, MC9S08PB8VTG application, or MC9S08PB8VTG equivalent, this page delivers verified technical context, package-specific pin assignments, functional peripheral mapping, and validated alternative options for cost-optimized, temperature-resilient embedded control designs requiring compact footprint and low-power stop modes.

Technical Context

The MC9S08PB8VTG implements an enhanced HCS08 CPU core with four-level nested interrupt support and up to 30 interrupt/reset sources. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with factory-trimmed internal reference (±0.2% resolution, ±1.5% deviation over –40 °C to 105 °C), enabling stable 20 MHz bus operation without external crystal.

Peripheral integration includes a 12-bit ADC with eight-level FIFO and hardware trigger, dual FTM modules (2-channel FTM0 + 6-channel FTM2), single-wire background debug interface, and system-level interconnect logic supporting hardware-triggered events between SCI, RTC, ADC, and timers - optimized for infrared communication, baudrate detection, and metering calibration.

FAQ

What is the maximum operating frequency of the MC9S08PB8VTG?

The MC9S08PB8VTG 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 is achieved using the internal ICS with FLL, which maintains stability without requiring an external crystal for basic operation.

Does the MC9S08PB8VTG support in-circuit debugging?

Yes, the MC9S08PB8VTG includes a single-wire background debug interface (BKGD/MS pin) with on-chip in-circuit emulator (ICE) functionality. It supports three hardware breakpoints and nine trigger modes, enabling full visibility into program flow and register states during live operation.

How many ADC channels does the MC9S08PB8VTG have, and what is their resolution?

The MC9S08PB8VTG features an 8-channel, 12-bit successive approximation ADC with 2.5 µs conversion time. It includes an eight-level FIFO, automatic compare function, optional hardware trigger, and supports operation in stop3 mode - all confirmed in the MC9S08PB16/PB8 datasheet Rev. 2.1.

What package type is used for the MC9S08PB8VTG?

The MC9S08PB8VTG is supplied in a 16-pin TSSOP package (JEDEC MO-153AC), with 0.65 mm lead pitch and 5.0 mm × 4.4 mm body dimensions. Thermal resistance is R_θJA = 130 °C/W on a single-layer board, as specified in Table 10 of the official datasheet.

Can the MC9S08PB8VTG operate in low-power stop mode?

Yes, the MC9S08PB8VTG supports a low-power stop3 mode with typical current consumption of 1.3 µA at 5 V (1.2 µA at 3 V). In this mode, only the 1 kHz LPO clock remains active, while the ADC, LVD, and RTC retain limited functionality - enabling ultra-low-power wake-on-event operation.
