Introduction

The C515A is a member of the Siemens C500 family of 8-bit microcontrollers. lt is functionally fully compatible with the SAB 80C515/83C515A-5 microcontrollers.

The C515A basically operates with internal and/or external program memory. The C515A-L is identical to the C515A-4R, except that it lacks the on-chip program memory. Therefore, in this documentation the term C515A refers to all versions within this specification unless otherwise noted.

Listed below is a summary of the main features of the C515A:

? Full upward compatibility with SAB 80C515A/83C515A-5

? Up to 24 MHz external operating frequency

– 500 ns instruction cycle at 24 MHz operation

? 32K byte on-chip ROM (with optional ROM protection)

– alternatively up to 64K byte external program memory

? Up to 64K byte external data memory

? 256 byte on-chip RAM

? 1K byte on-chip RAM (XRAM)

? On-chip emulation support logic (Enhanced Hooks Technology TM)

? Six 8-bit parallel I/O ports

? One input port for analog/digital input

? Full duplex serial interface (USART)

– 4 operating modes, fixed or variabie baud rates

? Three 16-bit timer/counters

– Timer 0 / 1 (C501 compatible)

– Timer 2 for 16-bit reload, compare, or capture functions

? 10-bit A/D converter

– 8 multiplexed analog inputs

– Built-in self calibration

? 16-bit watchdog timer

? Power saving modes

– Slow down mode

– Idle mode (can be combined with slow down mode)

– Software power down mode with wake-up capability through INT0 pin

– Hardware power down mode

? 12 interrupt sources (7 external, 5 internal) selectable at 4 priority levels

? ALE switch-off capability

? P-MQFP-80 packages

? Temperature Ranges : SAB-C515A-4R TA = 0 to 70 °C

SAF-C515A-4R TA = – 40 to 85 °C

SAH-C515A-4R TA = – 40 to 110 °C

SAK-C515A-4R TA = – 40 to 125 °C (max. frequency : 18 MHz)
