Product details
Overview
MC9S08PA16VTG 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 dual FlexTimer modules (6-channel + 2-channel), 12-bit 12-channel ADC, two LIN-capable SCIs, I²C, SPI, RTC, and analog comparator - deployed in automotive body control modules, industrial sensor nodes, and smart appliance motor controllers.
For engineers reviewing the MC9S08PA16VTG datasheet, MC9S08PA16VTG pinout, MC9S08PA16VTG application, or MC9S08PA16VTG equivalent, this page delivers verified electrical specs, validated package mapping (16-pin TSSOP), confirmed peripheral timing behavior, and real-world use-case implementation guidance - all traceable to Rev. 4 (03/2020) official technical data.
Technical Context
The MC9S08PA16VTG implements an enhanced S08 CPU core with four-level nested interrupt support and up to 40 interrupt/reset sources. Its clock system combines a precision internal clock source (ICS) with FLL-based frequency synthesis (±1% over 0–70 °C) and external crystal oscillator (XOSC) support for 4–20 MHz or 31.25–39.0625 kHz crystals.
System protection includes independent watchdog timer, programmable low-voltage detect (LVD) with four warning thresholds, illegal opcode/address detection, and flash/RAM access protection. Debug infrastructure features single-wire background debug interface (BKGD), three hardware breakpoints, and on-chip ICE with two comparators and nine trigger modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08PA16VTJ | Same core, memory, and peripherals; differs only in 20-pin TSSOP package (vs. 16-pin TSSOP) | Requires PCB redesign for additional GPIO (14 → 18 pins) and extra power/ground connections | Select VTJ when more I/O or ADC channels are needed; VTG suits space-constrained designs where 14 GPIO suffices |
| S9KEAZ128AMLH | Kinetis E-series ARM Cortex-M0+ core; 128 KB flash, 16 KB RAM, higher performance but larger footprint and higher cost | Targets next-generation designs requiring RTOS support, USB, or floating-point math - not drop-in compatible | Choose S9KEAZ128AMLH only for new designs needing scalability beyond 8-bit constraints; VTG remains optimal for cost-sensitive legacy upgrades |
Compared with MC9S08PA16VTG, the VTJ variant offers expanded I/O count in a larger package, while the S9KEAZ128AMLH provides architectural modernization at the expense of software migration effort and BOM cost - making VTG the most economical choice for established 8-bit control functions.

FAQ
What is the maximum operating frequency and voltage range for the MC9S08PA16VTG?
The MC9S08PA16VTG operates at up to 20 MHz bus frequency across a supply voltage range of 2.7 V to 5.5 V, with guaranteed performance over the full industrial temperature range of –40 °C to +105 °C. This specification is validated per Rev. 4 (03/2020) datasheet Section 5.4 and Table 3, and applies specifically to the VTG variant in 16-pin TSSOP packaging.
Does the MC9S08PA16VTG support in-circuit debugging, and what interface is used?
Yes, the MC9S08PA16VTG supports in-circuit debugging via its single-wire background debug (BKGD) interface on pin PTA4. It enables full breakpoint control, memory inspection, and register access without requiring dedicated JTAG pins - a key feature confirmed in Section 1.1 and Figure 1 of the MC9S08PA16 Series Data Sheet Rev. 4.
How many GPIO pins does the MC9S08PA16VTG provide, and which have enhanced drive capability?
The MC9S08PA16VTG provides 14 GPIO pins in its 16-pin TSSOP package (VTG suffix), including four ultra-high-current sink/source pins rated for 20 mA - specifically PTB4, PTB5, PTD0, and PTD1 as documented in Table 1 (Ordering Information) and Section 2.1 (Input/Output) of the datasheet.
Can the MC9S08PA16VTG operate in low-power modes while maintaining RTC or ADC functionality?
Yes, the MC9S08PA16VTG supports RTC operation and ADC conversions in Stop3 mode. The RTC runs from the 1 kHz LPO clock (adding <1 µA to total current), and the ADC can perform conversions with ADLPC = 1 and MODE = 10B configuration, increasing Stop3 current by only 40 µA at 5 V - details are specified in Table 5, row #7 of the Rev. 4 datasheet.
What package type and thermal characteristics apply to the MC9S08PA16VTG?
The MC9S08PA16VTG uses a 16-pin TSSOP package with a thermal resistance (RθJA) of 130 °C/W on single-layer board and 87 °C/W on four-layer board, per Table 10 in Rev. 4. Its operating junction temperature range is –40 °C to +125 °C, and it is rated for moisture sensitivity level (MSL) 3 per J-STD-020.
