FAQ

What is the maximum bus clock frequency supported by the S9S12VR16F0MLCR?

The S9S12VR16F0MLCR supports a maximum bus clock frequency of 25 MHz, achieved via its internal Phase-Locked Loop (PLL) using either the internal RC oscillator or an external crystal (1–8 MHz) as reference. This frequency defines the timing base for all peripherals including timers, PWM, and ADC conversions, and is validated across the full operating temperature range of −40°C to +125°C.

Does the S9S12VR16F0MLCR include a LIN physical layer transceiver?

Yes, the S9S12VR16F0MLCR integrates the S12LINPHYV2 module, a fully compliant LIN 2.1 physical layer transceiver. It supports slave-mode operation with automatic wake-up detection, sleep mode with ultra-low current consumption (<10 µA), and bus short-circuit protection - eliminating the need for an external LIN transceiver in most body electronics applications.

How many high-side and low-side drivers does the S9S12VR16F0MLCR provide?

The S9S12VR16F0MLCR provides four integrated high-side drivers (HSD0–HSD3) and four low-side drivers (LSD0–LSD3). Each driver includes overcurrent detection, thermal shutdown, and diagnostic flag reporting via dedicated status registers, enabling robust control of lamps, relays, and small motors without external driver ICs.

What is the role of the BATS module in the S9S12VR16F0MLCR?

The BATS (Battery Supply Sense) module in the S9S12VR16F0MLCR provides continuous monitoring of the vehicle battery voltage with 10-bit resolution and programmable threshold detection. It enables autonomous low-voltage response (e.g., entering sleep mode before brownout) and supports LIN-based battery status reporting without external ADC or voltage dividers.

Is the S9S12VR16F0MLCR pin-compatible with other devices in the MC9S12VR family?

Yes, the S9S12VR16F0MLCR is pin-compatible with other 48-pin LQFP variants in the MC9S12VR family, including S9S12VR32F0MLCR and S9S12VR64F0MLCR. Identical pin assignments for power, ground, LIN, HSDRV, LSDRV, ADC, and debug signals allow hardware reuse across firmware variants with different Flash sizes.
