8-Bit CMOS Microcontroller

The C515A is an upward compatible version of the SAB 80C515A/83C515A-5 8-bit microcontroller which additionally provides an improved 10-bit A/D converter, ALE switch-off capability, on-chip emulation support, ROM protection, and enhanced power saving mode capabilities. With a maximum external clock rate of 24 MHz it achieves a 500 ns instruction cycle time (1 µs at 12 MHz). The C515A is mounted in a P-MQFP-80 package.
