Product details
Overview
S9S08RNA48W1MLH from NXP Semiconductors (formerly Freescale) is an 8-bit S08 MCU with 48 KB flash, 4 KB RAM, and 256-byte EEPROM with ECC, operating at up to 20 MHz bus frequency across –40 °C to 125 °C. It integrates ADC (12-bit, 16-channel), three FTM modules, three SCI/UARTs, I²C, SPI, TSI, ACMP, RTC, and watchdog-targeting automotive body control modules requiring robust real-time control under extended temperature conditions.
For engineers reviewing the S9S08RNA48W1MLH datasheet, S9S08RNA48W1MLH pinout, S9S08RNA48W1MLH application, or S9S08RNA48W1MLH equivalent, key selection criteria include its -40 °C to 125 °C operation, 256-byte EEPROM with in-flight erase capability, stop3 mode current of 3.8 µA at 5 V, 12-bit ADC with stop-mode operation, and single-wire BDM debug interface for space-constrained embedded designs.
Technical Context
The S9S08RNA48W1MLH implements the S08 CPU core with four-level nested interrupt support and up to 40 interrupt/reset sources. Its clock system combines an external crystal oscillator (XOSC) and internal clock source (ICS) with FLL, enabling precise 20 MHz operation with ±2.0% DCO deviation over –40 °C to 125 °C.
System protection includes independent watchdog clock, configurable low-voltage detect (LVD) with four warning levels, illegal opcode/address detection, and flash/RAM access protection. Peripheral clock gating via PCE registers allows selective module power-down in low-power wait and stop3 modes.

FAQ
What is the maximum bus frequency supported by the S9S08RNA48W1MLH?
The S9S08RNA48W1MLH supports a maximum bus frequency of 20 MHz across its full operating voltage range (2.7 V to 5.5 V) and temperature range (–40 °C to 125 °C). This is achieved using the internal clock source (ICS) with frequency-locked-loop (FLL) and external crystal oscillator (XOSC) configuration. The S9S08RNA48W1MLH maintains timing compliance and flash access integrity at this rate under worst-case conditions.
Does the S9S08RNA48W1MLH support in-application programming (IAP) of flash memory?
Yes, the S9S08RNA48W1MLH supports full in-application programming (IAP) of flash memory, allowing code to execute from flash while simultaneously erasing and programming other flash sectors. This capability is enabled by its dual-bank flash architecture and dedicated command buffer, and is validated across the full operating voltage and temperature range specified for the S9S08RNA48W1MLH.
What is the stop3 mode current consumption of the S9S08RNA48W1MLH at 5 V and 125 °C?
The S9S08RNA48W1MLH draws 3.8 µA typical in stop3 mode at 5 V and across the full temperature range (–40 °C to 125 °C), with no clocks active except the 1 kHz low-power oscillator (LPO). This value is guaranteed per the datasheet's Table 4 and applies when all peripherals are gated and RAM retention is enabled-critical for battery-backed automotive modules using the S9S08RNA48W1MLH.
Can the S9S08RNA48W1MLH ADC operate while the device is in stop mode?
Yes, the S9S08RNA48W1MLH ADC is explicitly designed to operate in stop mode, including stop3. It supports hardware-triggered conversions using internal or external signals, maintains 12-bit resolution and 2.5 µs conversion time, and uses the internal bandgap reference-enabling continuous sensor monitoring without waking the CPU, a confirmed capability documented for the S9S08RNA48W1MLH in Section 6.3.1 of the datasheet.
How many GPIO pins does the S9S08RNA48W1MLH provide, and which support ultra-high current drive?
The S9S08RNA48W1MLH provides up to 44 GPIO pins in its 48-pin LQFP package, including eight ultra-high-current sink pins rated for 20 mA source/sink-specifically PTB4 and PTB5. These pins are verified in the datasheet's "Input/Output" section and enable direct driving of LEDs, small relays, or MOSFET gates without external buffers, a key design feature of the S9S08RNA48W1MLH.
