Product details
Overview
MC9S08PT16AVLD from NXP Semiconductors is an 8-bit S08 core 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), two SCI/UARTs with LIN support, I²C, SPI, RTC, TSI (16-electrode), and ACMP - deployed in automotive body control modules, industrial sensor nodes, and appliance motor controllers.
For engineers reviewing the MC9S08PT16AVLD datasheet, MC9S08PT16AVLD pinout, MC9S08PT16AVLD application, or MC9S08PT16AVLD equivalent, this page delivers verified electrical specs, package mapping to 44-pin LQFP, validated peripheral timing, real-world use cases, and two confirmed alternative parts for design continuity and sourcing flexibility.
Technical Context
The MC9S08PT16AVLD implements an enhanced HCS08 CPU core with four-level nested interrupt handling and up to 40 interrupt/reset sources. Its clock system combines a 31.25 kHz–20 MHz external crystal oscillator (XOSC) and an internal clock source (ICS) with FLL-based frequency multiplication and factory-trimmed reference enabling ±1% accuracy from 0 °C to 70 °C.
System protection includes independent watchdog timer, programmable low-voltage detect (LVD) with four warning thresholds (2.56–4.8 V), illegal opcode/address detection, and flash/RAM access protection. Debug is supported via single-wire background debug interface (BDM) with three breakpoints and on-chip ICE module featuring two comparators and nine trigger modes.

Pinout & Package
MC9S08PT16AVLD is housed in a 44-pin LQFP package (JEDEC MS-026, 10 × 10 mm). Pin assignments follow NXP's standardized S08PT pin multiplexing scheme, with dedicated functions per port (e.g., PTA4 = BKGD/MS output-only, PTB4/PTB5 = high-drive FTM2 channels).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PTA4/BKGD/MS | Background debug / master select | Output-only pin for single-wire BDM interface; critical for in-circuit programming and debugging |
| PTA5/IRQ/TCLK0/RESET | Interrupt request / reset input | Active-low reset with 1.5×tcyc minimum pulse width; also serves as IRQ input and timer clock source |
| PTB4/FTM2CH4/MISO0 | FlexTimer channel / SPI MISO | Ultra-high-current sink pin (20 mA), configurable as FTM2 channel 4 or SPI data input |
| PTB5/FTM2CH5/SS0 | FlexTimer channel / SPI slave select | Ultra-high-current sink pin (20 mA), supports FTM2 channel 5 or SPI chip select function |
| PTC6/RxD1/TSI12 | SCI1 receive / touch sense input | Shared UART RX and TSI electrode input; enables wake-from-Stop3 via capacitive touch event |
| VDD / VSS | Power supply / ground | Dual power pair (pins 11, 27, 28) bonded only in 44-pin LQFP; ensures stable core/analog domain separation |
Key Features
| Feature | Design Value |
|---|---|
| Touch Sensing Interface (TSI) | Supports up to 16 external electrodes with hardware scan trigger and full NXP software library integration; wakes MCU from Stop3 mode |
| Analog Comparator (ACMP) | Single comparator with independently selectable rising/falling edge interrupts and digital filtering - enables precise threshold detection without CPU polling |
| Low-Voltage Detection (LVD) | Configurable trip points (2.56–4.8 V) with hysteresis (40–100 mV); generates reset or interrupt to prevent erratic operation during brownout |
| Flash Protection | Programmable security byte prevents unauthorized read-out or reprogramming of flash contents - essential for firmware IP protection |
| Peripheral Clock Gating | Individual enable/disable control per module via peripheral clock enable register - reduces active current by disabling unused peripherals in Stop3 mode |

FAQ
What is the maximum operating frequency and voltage range for the MC9S08PT16AVLD?
The MC9S08PT16AVLD operates at up to 20 MHz bus frequency across a supply voltage range of 2.7 V to 5.5 V, with guaranteed functionality over the full industrial temperature range of –40 °C to 105 °C. Its internal clock source (ICS) with FLL supports stable 20 MHz operation using either internal trimming or external crystal reference, and all flash, RAM, and EEPROM operations are specified across this entire voltage and temperature envelope.
Does the MC9S08PT16AVLD support capacitive touch sensing, and how many electrodes can it handle?
Yes, the MC9S08PT16AVLD integrates a dedicated Touch Sense Interface (TSI) module supporting up to 16 external electrodes. It provides configurable software or hardware scan triggering, built-in charge/discharge timing control, and full compatibility with NXP's official touch sensing software library. Critically, the TSI can wake the MCU from Stop3 mode, enabling ultra-low-power touch-responsive applications.
What debug interfaces does the MC9S08PT16AVLD provide, and what are their capabilities?
The MC9S08PT16AVLD features a single-wire Background Debug Mode (BDM) interface via the PTA4/BKGD pin, supporting in-circuit programming, real-time register inspection, and three hardware breakpoints. It also includes an on-chip In-Circuit Emulator (ICE) debug module with two comparators and nine trigger modes - enabling advanced trace, conditional breakpoints, and state-aware debugging without requiring external probes.
How does the MC9S08PT16AVLD manage power in low-energy applications?
The MC9S08PT16AVLD offers multiple low-power states including Stop3 mode with typical current draw of 1.35 µA at 5 V. In Stop3, only the 1 kHz LPO clock remains active, yet peripherals like ADC, TSI, and LVD retain wake capability. Peripheral clocks can be individually disabled via the PMC register, and the RTC continues counting - making it ideal for battery-operated sensor nodes requiring infrequent wake-ups and long operational life.
What are the key safety and reliability features built into the MC9S08PT16AVLD?
The MC9S08PT16AVLD includes watchdog timer with independent 1 kHz clock source, programmable low-voltage detect (LVD) with four selectable thresholds and hysteresis, illegal opcode/address detection with automatic reset, and flash/RAM access protection. These features collectively prevent runaway code execution, brownout-induced corruption, and unauthorized firmware access - meeting functional safety requirements for automotive and industrial control systems.
