FAQ
What is the maximum bus frequency supported by the S9S08DN48F1MLF?
The S9S08DN48F1MLF supports a maximum bus frequency of 20 MHz, derived from its 40 MHz HCS08 CPU core via a 2:1 divider. This bus speed is maintained across the full operating voltage range (2.7–5.5 V) and temperature range (–40°C to +105°C), enabling deterministic real-time response in automotive and industrial environments where the S9S08DN48F1MLF is commonly deployed.
Does the S9S08DN48F1MLF include a hardware real-time counter (RTC)?
Yes, the S9S08DN48F1MLF includes a dedicated 8-bit real-time counter (RTC) module with binary or decimal prescaler options. It can operate using an external 32.768 kHz crystal for high-precision timekeeping or autonomously on the on-chip 1 kHz low-power oscillator - allowing the S9S08DN48F1MLF to perform cyclic wake-up and time-of-day functions without external timing components.
Can the S9S08DN48F1MLF execute code while erasing or programming EEPROM?
Yes, the S9S08DN48F1MLF supports concurrent execution and EEPROM operations: it can execute code from flash memory while erasing or programming its 2 KB EEPROM. The EEPROM supports 4-byte dual-page or 8-byte single-page erase sectors, and the S9S08DN48F1MLF includes erase abort functionality to preserve data integrity during unexpected power loss.
What LIN protocol versions does the SCI module in the S9S08DN48F1MLF support?
The SCI1 module in the S9S08DN48F1MLF is explicitly designed to support LIN 2.0 Protocol and SAE J2602 compliance. It provides master extended break generation, slave extended break detection, and active-edge wakeup - all required for interoperability with standard LIN transceivers and network masters. This makes the S9S08DN48F1MLF suitable for certified LIN slave node implementations.
Is the S9S08DN48F1MLF pin-compatible with other members of the MC9S08DN family?
Yes, the S9S08DN48F1MLF is pin-compatible with the MC9S08DN60F1MLF, MC9S08DN32F1MLF, and MC9S08DN16F1MLF in the 48-pin LQFP package variant. All share identical pin assignments, electrical characteristics, and peripheral mapping - enabling scalable memory selection (16 KB to 60 KB flash) without PCB redesign. The S9S08DN48F1MLF maintains full functional compatibility within this footprint.
