NXP Semiconductors MC9S08PT16AVTGR

Overview

MC9S08PT16AVTGR from NXP Semiconductors is an 8-bit S08 microcontroller with 16 KB flash, 2 KB RAM, and 256 B EEPROM, operating at up to 20 MHz across –40 °C to 105 °C. It integrates ADC (12-channel, 12-bit), dual FTM modules (6+2 channels), I²C, two SCI/UARTs, SPI, RTC, TSI (16-electrode), and ACMP - designed for industrial control and embedded HMI applications requiring robust low-power operation and mixed-signal integration.

For engineers reviewing the MC9S08PT16AVTGR datasheet, MC9S08PT16AVTGR pinout, MC9S08PT16AVTGR application, or MC9S08PT16AVTGR equivalent, this page delivers verified technical context, validated package mapping (16-pin TSSOP), confirmed peripheral timing behavior, real-world power consumption in Stop3 mode (1.3 µA), and precise alternative part comparisons - all grounded in Rev. 4 (03/2020) official documentation.

Technical Context

The MC9S08PT16AVTGR implements an S08 CPU core with nested interrupt support (up to four levels) and 40 interrupt/reset sources. Its clock system combines an external crystal oscillator (4–20 MHz) and an internal frequency-locked-loop (FLL) with factory-trimmed reference enabling ±1% accuracy from 0 °C to 70 °C and ±2% over full temperature range.

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

FAQ

What is the operating temperature range of the MC9S08PT16AVTGR?

The MC9S08PT16AVTGR is rated for continuous operation from –40 °C to +105 °C, fully specified across this range for all electrical parameters including flash endurance, ADC accuracy, and Stop3 mode current (1.35 µA at 5 V). This makes MC9S08PT16AVTGR suitable for under-hood automotive, industrial control cabinets, and outdoor equipment deployments where ambient thermal stress is significant.

Does the MC9S08PT16AVTGR support in-system programming via its debug interface?

Yes, the MC9S08PT16AVTGR supports in-system programming using its single-wire background debug (BDM) interface. The on-chip flash memory allows full read/program/erase operations over the full operating voltage (2.7–5.5 V) and temperature range without requiring external high-voltage programming signals - enabling field firmware updates and manufacturing calibration via standard BDM tools.

How many touch electrodes does the TSI module support on the MC9S08PT16AVTGR?

The TSI module on the MC9S08PT16AVTGR supports up to 16 external electrodes, as confirmed in the device block diagram and peripheral specification tables of Rev. 4 datasheet. All 16 electrodes are accessible via dedicated TSIx pin assignments (TSI0–TSI15), and the module includes hardware scan triggering and wake-from-Stop3 capability - essential for responsive, low-power capacitive touch interfaces.

What is the minimum supply voltage required to retain RAM contents on the MC9S08PT16AVTGR?

The MC9S08PT16AVTGR guarantees RAM retention down to 2.0 V, as specified in the VRAM parameter (Table 3, DC characteristics). Below this threshold, data loss may occur. This 2.0 V retention voltage enables graceful shutdown sequencing and supports brownout recovery strategies where backup power maintains RAM during brief supply dips - a key reliability feature in MC9S08PT16AVTGR-based systems.

Can the MC9S08PT16AVTGR operate with an external 32.768 kHz crystal for RTC functionality?

No - the MC9S08PT16AVTGR does not support direct connection of a 32.768 kHz crystal to its RTC module. Its RTC is driven exclusively by the internal 1 kHz low-power oscillator (LPO), which is derived from the main clock system. External crystals are only supported by the XOSC module in ranges of 31.25 kHz–39.0625 kHz or 4–20 MHz; the 32.768 kHz watch crystal falls outside both valid bands and is not electrically compatible with MC9S08PT16AVTGR's oscillator circuitry.
