Product details
Overview
MC9S08PA4VTGR from NXP Semiconductors is an 8-bit S08 microcontroller designed for cost-sensitive embedded control applications, featuring a 20 MHz bus frequency across 2.7–5.5 V supply and –40°C to +105°C operating range, 4 KB flash, 512 byte RAM, and 128 byte EEPROM with in-circuit programmability. It integrates an 8-channel 12-bit ADC, three 2-channel FlexTimer modules, SCI UART with LIN support, RTC, analog comparator, and keyboard interrupt module - deployed in motor control subsystems, industrial sensor interfaces, and appliance power management.
For engineers reviewing the MC9S08PA4VTGR datasheet, MC9S08PA4VTGR pinout, MC9S08PA4VTGR application, or MC9S08PA4VTGR equivalent, this page delivers verified technical context, validated pin assignments for the 20-pin TSSOP package, real-world use cases with design-value metrics, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The MC9S08PA4VTGR implements an enhanced HCS08 core with four-level nested interrupt handling and up to 40 interrupt/reset sources, enabling deterministic real-time response in resource-constrained systems. Its clock system combines an external crystal/ceramic oscillator (31.25 kHz–20 MHz) with an internal frequency-locked loop (FLL) offering ±1% accuracy over 0°C–70°C and ±2% across full temperature range.
System protection includes an independent watchdog timer, selectable low-voltage detect/warning thresholds (e.g., VLVDH = 4.3 V), illegal opcode/address detection, and flash/RAM access protection. Peripherals operate under unified system integration module (SIM) control, with debug support via single-wire background debug interface and on-chip ICE with two comparators and nine trigger modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08PA4AVTJ | Same silicon, identical electrical specs and pinout; differs only in mask set revision (A vs blank) - no functional impact per NXP Rev. 10 datasheet note. | Qualified for new designs per NXP recommendation; shares same 20-pin TSSOP package and thermal profile. | Select MC9S08PA4AVTJ if sourcing new-design-qualified mask version; otherwise MC9S08PA4VTJ remains fully compatible. |

FAQ
What is the maximum operating frequency and voltage range for the MC9S08PA4VTGR?
The MC9S08PA4VTGR 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 NXP's MC9S08PA4 Data Sheet Rev. 10, Table 7, and supports stable execution in battery-powered and wide-input industrial systems without external voltage regulation beyond basic filtering.
Does the MC9S08PA4VTGR support in-application programming (IAP) of its flash memory?
Yes, the MC9S08PA4VTGR supports full read/program/erase operations on its 4 KB flash memory while executing code from other flash regions - enabling firmware updates and parameter reconfiguration without halting system operation. This capability is explicitly documented in the "On-chip memory" section of the MC9S08PA4 datasheet and leverages dedicated flash command registers and protection mechanisms to prevent accidental corruption.
How many analog-to-digital converter (ADC) channels does the MC9S08PA4VTGR provide, and what is its resolution?
The MC9S08PA4VTGR features an 8-channel, 12-bit successive-approximation ADC with 2.5 µs conversion time, internal bandgap reference, and optional hardware triggering. It supports operation in stop mode and includes data buffers with watermark interrupt capability - allowing precise sensor sampling in low-power applications without CPU intervention. These specifications are confirmed in Section 7.3.1 of the official datasheet.
What debug interface does the MC9S08PA4VTGR use, and how many breakpoints are supported?
The MC9S08PA4VTGR uses a single-wire background debug (BKGD) interface compliant with NXP's BDM protocol, supporting up to three hardware breakpoints during in-circuit debugging. It also integrates an on-chip in-circuit emulator (ICE) module with two comparators and nine trigger modes - enabling advanced trace and state inspection without requiring external debug probes or additional pins beyond BKGD/MS and VDD/VSS.
Is the MC9S08PA4VTGR pin-compatible with other members of the MC9S08PA4 family, such as MC9S08PA4AVTJ?
Yes, the MC9S08PA4VTGR is fully pin-compatible with MC9S08PA4AVTJ - both use the identical 20-pin TSSOP package with matching pin assignments, electrical characteristics, and thermal profiles. The only difference is mask set revision (blank vs A), which NXP confirms has no functional impact and recommends the 'A' version for new designs per Rev. 10 datasheet Section 3.3.
