C517A

The C517A is a high-end member of the Siemens C500 family of 8-bit microcontrollers. lt is functionally fully compatible with the SAB-80C517A/83C537A-5 microcontrollers. The C517A basically operates with internal and/or external program memory. The C517A-L is identical to the C517A-4R, except that it lacks the on-chip program memory. Therefore, in this documentation the term C517A refers to all versions within this specification unless otherwise noted. Following is a summary of the main features of the C517A: (1)full upward compatibility with SAB 80C517A/83C517A-5; (2)up to 24 MHz external operating frequency-500 ns instruction cycle at 24 MHz operation; (3)superset of the 8051 archoitecture with 8 datapointers; (4)32K byte on-chip ROM (with optional ROM protection)-alternatively up to 64K byte external program memory; (5)up to 64K byte external data memory; (6)256 byte on-chip RAM; (7)2K byte on-chip RAM (XRAM); (8)seven 8-bit parallel I/O ports; (9)two input ports for analog/digital input.

What comes next is about C517A maximum ratings: (1)ambient temperature under bias (TA): 40 °C to + 110 °C; (2)storage temperature (TST): 65 °C to + 150 °C; (3)voltage on VCC pins with respect to ground (VSS): 0.5 V to 6.5 V; (4)voltage on any pin with respect to ground (VSS): 0.5 V to VCC + 0.5 V; (5)input current on any pin during overload condition: 10 mA to + 10 mA; (6)absolute sum of all input currents during overload condition:| 100 mA |; (7)power dissipation: TBD

The following is about C517A electrical characteristics: (1)input low voltages: - 0.5V min and 0.2 VCC - 0.1V max; (2)input high voltages: 0.7 VCC min and VCC + 0.5V max; (3)output low voltages: 0.45V max at IOL = 1.6 mA, IOL = 3.2 mA; (4)output high voltages: 2.4V min at IOH = - 80A; (5)logic 0 input current: -10A min and -70A max at VIN = 0.45 V; (6)logical 0-to-1 transition current: -65 A min and -650A max at VIN = 2 V; (7)input leakage current: ±1A max at 0.45 < VIN < VCC; (8)input low current: -100A max at VIN = 0.45 V; (9)pin capacitance: 10 pF max at fc = 1 MHz, TA = 25 °C; (10)overload current: ±5 mA max; (11)programming voltage: 10.9V min and 12.1V max at 11.5 V ± 5%; (12)C517A power supply current: TBD at VCC = 5 V; (13)power supply current at EA/VPP in programming mode: 30 mA max.
