µPac 515C

• CPU: Infineon C515C with 10.00 MHz crystal speed, which has an internal equivalent clock of 20 MHz. Improved architecture results in 600 nS instruction cycle time at 10.00 MHz crystal speed.
• CAN MODULE: It is a full CAN module version 2.0 B active with 15 message objects and basic-CAN feature with data rates approaching 1 MBaud. The module has 256 register/data bytes allocated in external data memory area.
• DIGITAL I/O: 19 TTL level, bit programmable I/O lines, 8 high current outputs, with an additional 2 inputs and 3 output lines available with the purchase of the DUART upgrade option. There is a 50 pin I/O rack compatible header connector which allows connection to 24 of these I/O lines (consisting of the 8 high current outputs, 11 TTL level programmable lines and the optional 2 inputs and 3 outputs). When the CAN option and coprocessor are not installed, an additional 8 TTL level, bit programmable I/O lines are available on a 10 pin header. 
• ANALOG INPUTS: Fast 8 channel, 10 bit analog to digital converter with a 10.4 microsecond conversion rate. A/D inputs may be also be used as an addition 8 digital inputs. 
• ANALOG OUTPUTS: The optional D/A has 4 channels with 8 bit resolution. 
• COUNTER/TIMERS/PWM: Three, 16 bit counter/timers are included standard. One of these has four I/O lines which can be used as compare outputs, or capture inputs (for Pulse Width Modulation/Demodulation). A watchdog timer is also provided. An additional 16 bit counter/timer is included with purchase of the coprocessor option.
• COMMUNICATION: The 515C is capable of supporting up to 4 RS232 serial ports, 1 is standard and 3 are included with the purchase of optional upgrades. Conversion of up to 3 ports from RS232 to RS-422/485 is available optionally. 
• COPROCESSOR: An optional coprocessor may be added which is preprogrammed to provide an additional RS232 serial port with transmit and receive data buffering and a keypad interface (for decoding up to 20 keys in a 4x5 matrix). This coprocessor may be custom programmed by EMAC for almost unlimited capabilities. Resources available on the coprocessor: 255 bytes of RAM, a UART, two 16 bit timer/counters with counter inputs, 2 interrupt inputs, 15 I/O lines, and an analog comparator. 
• LCD INTERFACE: The interface will drive all industry-standard character displays based on the HD44780 and compatibles. It will also drive all industry-standard graphic displays based on the the HD61830 and compatibles. 
• PERIPHERAL EXPANSION: The address bus, data bus, reset and interrupt lines are included on a 50 pin bus expansion header for connecting to external peripherals from EMAC, or to peripherals of your own design. 
• MEMORY: In addition to the 255 bytes of IRAM and 2K of XRAM memory within the C515C, there is provision for up to 128 K of EPROM or in-circuit programmable FLASH and up to 512 K of RAM. Total memory capacity is 640K bytes. The C515C directly accesses 128 K of memory (64K EPROM and 64K RAM) with the balance being Banked Selected memory. A parameter storage area is implemented with a 1K bit serial EEPROM. The EEPROM is a nonvolatile memory organized into 64, 16 bit words with over 10,000 write cycles guaranteed and unlimited read cycles. 
• DISTRIBUTION CD: A CD is included with a demo program in assembly language and drivers for the onboard peripherals. 
• THIRD PARTY SOFTWARE: The C515C is supported by Keil Software's C-compiler and their RTOS has a CAN API. A more economical DDS ANSI C subset compiler is also available as an alternative. There are C drivers for the onboard peripherals.
