Features (cont’d):

•8-bit A/D converter – 8 multiplexed analog inputs – Programmable reference voltages
•16-bit watchdog timer
•Power saving modes – Idle mode – Slow down mode (can be combined with idle mode) – Software power-down mode
•12 interrupt sources (7 external, 5 internal) selectable at four priority levels
•On-chip emulation support logic (Enhanced Hooks TechnologyTM)
•ALE switch-off capability
•P-MQFP-80-1 package
•Temperature Ranges : SAB-C515
TA= 0 to 70°C SAF-C515TA= -40 to 85°C SAH-C515TA= -40 to 110°C (max. operating frequency: 16 MHz)

The C515 is an upward compatible version of the SAB 80C515A 8-bit microcontroller which additionally provides ALE switch-off capability, on-chip emulation support, ROM protection, and slow down mode capability. With a maximum external clock rate of 24 MHz it achieves a 500 ns
instruction cycle time (1µs at 12 MHz). The C515 is mounted in a P-MQFP-80 package.
