FAQ
What is the maximum operating frequency of the MC908AZ60AVFUR2?
The MC908AZ60AVFUR2 achieves a maximum bus frequency of 40 MHz using its internal PLL, which multiplies an external crystal input (1–8 MHz). This frequency is sustained across the full operating temperature range (−40°C to +125°C) and supply voltage (4.5 V to 5.5 V), enabling deterministic real-time response in demanding automotive control loops.
Does the MC908AZ60AVFUR2 support in-system programming (ISP)?
Yes, the MC908AZ60AVFUR2 includes a factory-programmed 1 KB Monitor ROM (MON) that enables in-system programming via the SCI interface without requiring external debug hardware. This allows field firmware updates using standard UART connections and supports secure bootloaders with checksum verification before Flash writes.
How does the MC908AZ60AVFUR2 handle power-supply brown-out conditions?
The MC908AZ60AVFUR2 integrates a Low-Voltage Inhibit (LVI) circuit with four user-selectable reset thresholds (4.05 V, 4.25 V, 4.45 V, 4.65 V). When VDD drops below the configured threshold, LVI asserts a hardware reset to prevent Flash corruption or erratic operation - critical for automotive applications where battery voltage fluctuates during cranking.
Can the MC908AZ60AVFUR2 emulate EEPROM functionality?
Yes, the MC908AZ60AVFUR2 includes two dedicated EEPROM modules (EEPROM-1 and EEPROM-2), each supporting 1 KB of emulated nonvolatile storage. These modules implement wear leveling, atomic write/erase operations, and power-loss recovery - enabling reliable data logging and parameter storage without external EEPROM chips.
Is the MC908AZ60AVFUR2 pin-compatible with other HCS08 devices?
The MC908AZ60AVFUR2 uses a 64-pin LQFP package with standardized HCS08 port mapping, making it pin-compatible with MC9S08DZ60 and MC9S08DZ48 in the same package variant. However, register-level differences in peripherals like MSCAN and CGM require firmware adaptation even when pinouts match.
