FAQ

What is the maximum operating frequency of the S9S08DN32F1MLC CPU core?

The S9S08DN32F1MLC CPU core operates at a maximum frequency of 40 MHz, with a corresponding bus clock of up to 20 MHz. This performance level is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PLL or FLL mode. The S9S08DN32F1MLC maintains full functionality-including Flash access, ADC conversion, and peripheral operation-at this speed across its specified voltage (2.7–5.5 V) and temperature (–40°C to +105°C) range.

Does the S9S08DN32F1MLC support LIN 2.0 communication natively?

Yes, the S9S08DN32F1MLC includes a dedicated SCI module that fully supports LIN 2.0 and SAE J2602 protocols. Its hardware features include master-mode extended break generation, slave-mode break detection, and wakeup-on-active-edge functionality-enabling direct integration into automotive LIN networks without external transceivers. The S9S08DN32F1MLC's SCI is configured via standard register sets and requires no external protocol stack hardware.

How much EEPROM does the S9S08DN32F1MLC provide, and what are its endurance characteristics?

The S9S08DN32F1MLC integrates 2 KB of on-chip EEPROM with guaranteed endurance of at least 100,000 erase/write cycles per sector. It supports 4-byte dual-page or 8-byte single-page erase operations and allows program/erase while executing Flash code. The S9S08DN32F1MLC also includes EEPROM security features such as block protection and write-enable control via dedicated status registers.

What power-saving modes are available on the S9S08DN32F1MLC?

The S9S08DN32F1MLC offers three primary low-power modes: Wait mode (reduced power with clocks active), Stop2 (very low power with most clocks halted), and Stop3 (lowest power with 1 kHz RTI running from internal oscillator). In Stop3 mode, the S9S08DN32F1MLC draws less than 1.5 µA and retains RAM contents, enabling fast wake-up for time-triggered sensor sampling or LIN message response.

Is the S9S08DN32F1MLC pin-compatible with other devices in the MC9S08DN family?

Yes, the S9S08DN32F1MLC is pin-compatible with MC9S08DN60F1MLC, MC9S08DN48F1MLC, and S9S08DN16F1MLC in the 48-pin LQFP package. All share identical pin assignments, electrical characteristics, and peripheral mappings-only Flash (32 KB), EEPROM (2 KB), and RAM (2 KB) sizes differ. This allows scalable design reuse across product tiers without PCB redesign.
