ADI's ADM1232A is a microprocessor (MPU) and microcontroller (MCU) supervisor that can detect strobe pulse widths as narrow as 20 ns. This device monitors micro-processor supply voltage and can detect if a microprocessor has locked up or an external interrupt has been issued. This supervisor comes in both 8- and 16-lead packages and has an operational temperature range of -40°C to +85°C. The ADM1232 is ideal for monitoring microprocessors or microcontrollers in computer, automotive, and portable applications.
