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 (1 µs at 12 MHz). The C515 is mounted in a P-MQFP-80 package.
