NXP Semiconductors MC9S08PA60VLC

Overview

MC9S08PA60VLC from NXP (formerly Freescale) is an 8-bit HCS08L-core microcontroller with 60 KB on-chip flash, 4 KB RAM, and 256 B EEPROM, operating from 2.7–5.5 V across –40°C to +105°C. It integrates a 12-bit ADC (16 channels), three serial interfaces (SCI, SPI, I²C), internal clock generator, and low-voltage detect for industrial control and sensor interface applications.

For engineers reviewing the MC9S08PA60VLC datasheet, MC9S08PA60VLC pinout, MC9S08PA60VLC application, or MC9S08PA60VLC equivalent, key selection considerations include its LQFP-64 package, 57 GPIOs, 12-bit ADC resolution, industrial temperature range, and support for multiple synchronous/asynchronous communication protocols.

Technical Context

The MC9S08PA60VLC implements the S08 core architecture with a 0.18 µm process, delivering deterministic interrupt response and efficient C-language execution. It features a programmable internal clock generator supporting frequencies up to 40 MHz system clock (derived from internal reference or external crystal), and includes power management modes (wait, stop, and very-low-power stop) for embedded systems requiring low active and standby current.

Its peripheral set includes a 16-channel 12-bit ADC with hardware trigger capability, three independent serial modules (two SCI, one SPI, one I²C), and dedicated reset sources including POR and low-voltage detect. All peripherals are memory-mapped and accessible via standard HCS08 register addressing.

FAQ

What is the maximum bus frequency supported by the MC9S08PA60VLC?

The MC9S08PA60VLC supports a maximum bus frequency of 20 MHz, derived from its internal clock generator or external crystal source. This corresponds to a 40 MHz core clock when using the internal PLL divider setting. The device's timing specifications-including ADC conversion time and serial interface baud rates-are validated at this maximum frequency, ensuring deterministic real-time performance in control loops.

Does the MC9S08PA60VLC include hardware debug support?

Yes, the MC9S08PA60VLC includes background debug mode (BDM) support via a single-wire interface, enabling full in-circuit debugging, flash programming, and real-time register inspection without halting system operation. This capability is implemented in silicon and requires only the BDM pin (typically PTB0) and compatible debugger hardware such as the NXP Multilink or OSJTAG adapters.

Can the MC9S08PA60VLC operate without an external crystal?

Yes, the MC9S08PA60VLC can operate without an external crystal thanks to its integrated internal clock generator (ICG), which provides a trimmed internal reference clock (±2% accuracy) and supports FLL/PLL-based multiplication. This allows full functionality-including ADC sampling, serial communication, and timer operations-at 20 MHz bus speed, eliminating crystal cost and board area in many applications.

How many I/O pins does the MC9S08PA60VLC have, and are they all individually configurable?

The MC9S08PA60VLC provides 57 general-purpose I/O pins across Ports A–D, all individually configurable as digital inputs, outputs, or peripheral function assignments. Each pin supports software-selectable pull-up resistors, slew rate control, and interrupt-on-change capability. Pin multiplexing is managed via register settings, allowing flexible allocation between GPIO and peripheral functions like SCI, SPI, I²C, and ADC inputs.

Is the MC9S08PA60VLC RoHS compliant and halogen free?

Yes, the MC9S08PA60VLC is RoHS compliant and halogen free, meeting EU Directive 2011/65/EU and IEC 61249-2-21 standards. Its LQFP-64 package uses e3 termination finish (matte tin), has Moisture Sensitivity Level 3 (MSL3), and is rated for peak reflow temperatures up to 260°C for 40 seconds-ensuring compatibility with standard lead-free assembly processes.
