7 / 137 page Semiconductor Group 2 - 1 2 Fundamental Structure The SAB 80C517A/83C517A-5 is a high-end member of the Siemens SAB 8051 family of microcontrollers. It is designed in Siemens ACMOS technology and based on the SAB 8051 architecture. ACMOS is a technology which combines high-speed and density characteristics with low-power consumption or dissipation. While maintaining all the SAB 80C517 features and operating characteristics the SAB 80C517A is expanded in its "fail-safe" characteristics and timer capabilities. Furthermore, the SAB 80C517A additionally contains 2 kByte of on-chip RAM (called XRAM), a 10bit A/D converter with 12 multiplexed inputs, enhanced Baud Rate Generators and the capabilities of the Compare Capture Unit are improved. The SAB 80C517A is identical with the SAB 83C517A-5 except that it lacks the on-chip program memory. The SAB 80C517A / 83C517A-5 is supplied in a 84-pin plastic leaded chip carrier package (P-LCC-84) and in a 100-pin plastic metric rectangular flat package (P-MRFP-100). The essential enhancements to the SAB 80C517 are: – Additional 2KByte RAM on chip. – 32 kByte on-chip program memory (SAB 83C517A-5 only) – 12-channel 10-bit A/D Converter – Additional Compare Mode for Concurrent Compare function at Port 5; up to eight pins on P5 can be either set or reset on a compare match in two additional compare registers. – Dedicated interrupt vector for the 16-bit compare registers CM0-CM7: Interrupt requested on a compare match in one of the eight compare channels (eight request flags are available) – New baud rate generator for Serial Channel 0 – Expanded baud rate range for Serial Channel 1 – Hardware controlled Power Down Mode – Improved functionality of the Oscillator Watchdog – High speed operation of the device (up to 18 MHz crystal frequency) Figure 2-1 shows a block diagram of the SAB 80C517A Fundamental Structure |
