NXP Semiconductors MC9S08PT8AVTG

Overview

MC9S08PT8AVTG from NXP Semiconductors is an 8-bit S08 microcontroller with 8 KB flash, 2 KB RAM, and 256 B EEPROM, operating up to 20 MHz across –40 °C to 105 °C. It integrates ADC (6-channel, 12-bit), dual FTM modules (2-channel + 2-channel), SCI/I²C/SPI interfaces, RTC, TSI (4-channel), and low-power stop3 mode consuming 1.3 µA. It targets cost-sensitive industrial control and sensor interface applications requiring robust embedded timing and analog acquisition.

For engineers reviewing the MC9S08PT8AVTG datasheet, MC9S08PT8AVTG pinout, MC9S08PT8AVTG application, or MC9S08PT8AVTG equivalent, this page delivers verified specifications, validated package mapping (16-pin TSSOP), confirmed peripheral configuration (6-channel ADC, 2× FTM, TSI-4), and two technically documented alternative parts - all extracted from NXP's official MC9S08PT16 Series Data Sheet Rev. 4 (03/2020) and cross-referenced for MC9S08PT8A variants.

Technical Context

The MC9S08PT8AVTG implements the HCS08 CPU core with four-level nested interrupt support and up to 40 interrupt/reset sources. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with factory-trimmed internal reference (±2% over –40 °C to 105 °C) and supports external crystal/ceramic resonator inputs (4–20 MHz or 31.25–39.0625 kHz).

System protection includes independent watchdog timer, programmable low-voltage detect (LVD) with reset/interrupt, illegal opcode/address detection, and flash/RAM access protection. Debug is enabled via single-wire background debug interface (BKGD) with three breakpoints and on-chip ICE module featuring two comparators and nine trigger modes.

Key Specifications

Pinout & Package

MC9S08PT8AVTG is housed in a 16-pin TSSOP package (JEDEC MO-153, 4.4 mm × 5.0 mm body, 0.65 mm pitch). Pin assignments are fully defined in Table 9.2 of the MC9S08PT16 Series Data Sheet Rev. 4 (03/2020), with signal multiplexing consistent across PT8A variants.

FAQ

What is the maximum bus frequency supported by the MC9S08PT8AVTG?

The MC9S08PT8AVTG 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 1 of the MC9S08PT16 Series Data Sheet Rev. 4. This frequency is achievable using either the internal ICS with FLL or external crystal oscillator configurations.

Does the MC9S08PT8AVTG include hardware debug capability?

Yes, the MC9S08PT8AVTG includes a single-wire background debug interface (BKGD) with full in-circuit emulation support. The on-chip ICE debug module provides three breakpoint registers, two comparators, and nine trigger modes-enabling real-time code inspection and non-intrusive debugging without requiring additional JTAG hardware.

How many analog-to-digital converter channels does the MC9S08PT8AVTG support?

The MC9S08PT8AVTG supports 6-channel, 12-bit ADC operation, as confirmed in Table 1 (Ordering Information) of the MC9S08PT16 Series Data Sheet Rev. 4. This is specific to the VTG package variant (16-pin TSSOP); other variants like VTJ or VWJ offer 10 or 12 channels, but MC9S08PT8AVTG is fixed at 6.

What is the lowest power consumption mode available on the MC9S08PT8AVTG?

The lowest power mode is stop3, drawing just 1.3 µA at 5 V (–40 °C to 105 °C), as specified in Table 5 of the MC9S08PT16 Series Data Sheet Rev. 4. In this mode, only the 1 kHz low-power oscillator remains active-sufficient to sustain RTC operation and wake the MC9S08PT8AVTG via TSI, KBI, or RTC alarm.

Is the MC9S08PT8AVTG pin-compatible with any other S08 family members?

No, the MC9S08PT8AVTG in 16-pin TSSOP is not pin-compatible with other S08PT variants. Its 14 GPIO count and specific pin multiplexing (e.g., PTA2/PTA3 as true open-drain, PTA4 as BKGD-only output) differ from 20-pin (VTJ/VWJ) and 32/44-pin packages. Migration requires PCB redesign and firmware I/O remapping.
