NXP Semiconductors MC9S08PA60AVLDR

Overview

MC9S08PA60AVLDR from NXP Semiconductors is an 8-bit S08 microcontroller with 60 KB flash, 4 KB RAM, and 256 B EEPROM, operating at up to 20 MHz across –40 °C to 105 °C. It integrates a 16-channel 12-bit ADC, three FlexTimer modules (6+2+2 channels), three SCI/LIN UARTs, I²C, dual SPI, RTC, CRC, analog comparator, and keyboard interrupt modules. It serves as a main control unit in automotive body electronics and industrial sensor nodes requiring robust timing, low-power stop modes, and mixed-signal integration.

For engineers reviewing the MC9S08PA60AVLDR datasheet, MC9S08PA60AVLDR pinout, MC9S08PA60AVLDR application, or MC9S08PA60AVLDR equivalent, key selection criteria include its 20 MHz bus frequency at 2.7–5.5 V, 64-pin LQFP package with 57 GPIOs (including eight 20 mA sink/source pins), integrated watchdog and low-voltage detection, and support for in-circuit debugging via single-wire background interface.

Technical Context

The MC9S08PA60AVLDR implements an enhanced HCS08 CPU core with four-level nested interrupt handling and up to 40 interrupt/reset sources. Its clock system combines an external crystal oscillator (4–20 MHz or 31.25–39.0625 kHz) with an internal clock source featuring a frequency-locked loop (FLL) and factory-trimmed reference enabling ≤2% deviation over –40 °C to 105 °C.

Power management includes Stop3 mode with ~1.45 µA supply current (5 V), plus peripheral clock gating via PMC register to disable unused module clocks. System protection comprises independent watchdog clock, programmable low-voltage detect with four warning thresholds, illegal opcode/address reset, and flash/RAM access protection.

FAQ

What is the maximum operating frequency and voltage range for the MC9S08PA60AVLDR?

The MC9S08PA60AVLDR operates at up to 20 MHz bus frequency across a supply voltage range of 2.7 V to 5.5 V and a temperature range of –40 °C to 105 °C. This specification is guaranteed by production testing and applies to all core and peripheral functions, including flash execution, ADC conversion, and FTM PWM generation. The internal clock source (ICS) with FLL maintains stability within ±2% over the full temperature range.

Does the MC9S08PA60AVLDR support in-circuit debugging, and what interface does it use?

Yes, the MC9S08PA60AVLDR supports in-circuit debugging via a single-wire background debug interface using the BKGD/MS pin. It includes an on-chip in-circuit emulator (ICE) with two comparators and nine trigger modes, enabling breakpoints, watchpoints, and real-time trace. The MC9S08PA60AVLDR also supports three hardware breakpoints during active debugging sessions without requiring external JTAG hardware.

How many analog-to-digital converter (ADC) channels does the MC9S08PA60AVLDR have, and what is its resolution?

The MC9S08PA60AVLDR features a 16-channel, 12-bit successive-approximation ADC with a typical conversion time of 2.5 µs. It supports optional hardware triggering, data buffering with watermark flags, automatic compare functions, and operation in Stop3 mode. An internal bandgap reference channel is included, and the ADC remains functional during low-power states when configured appropriately.

What low-power modes are available on the MC9S08PA60AVLDR, and what is the lowest current consumption?

The MC9S08PA60AVLDR offers multiple low-power modes, including Wait mode and Stop3 mode. In Stop3 mode-with only the 1 kHz LPO clock active-the device draws just 1.45 µA at 5 V and –40 °C to 105 °C. Additional current adders apply for enabled peripherals: +44 µA for ADC, +130 µA for LVD monitoring. Clock gating via the PMC register further reduces active-mode current by disabling unused peripheral clocks.

Is the MC9S08PA60AVLDR pin-compatible with other members of the S08 PA family?

Yes, the MC9S08PA60AVLDR is pin-compatible with other 64-pin LQFP variants in the S08 PA family, including the MC9S08PA32AVLDR. Both share identical pin assignments, peripheral mappings, and electrical characteristics in the 64-pin package. However, differences exist in flash size (60 KB vs. 32 KB), ADC channel count (16 vs. 12 in smaller packages), and mask revision-requiring verification of memory and feature requirements before substitution.
