Proton ChipDrive Mobile Development System from Crownhill Associates Limited

Put your knowledge of PICmicros™ and Smartcards to good use with the PROTON ChipDrive Mobile. This smart and compact handheld unit and a copy of Proton PICBASIC Development Suite is all you need to develop professional Smartcard applications. The Proton-CDM is a terminal providing a ready built platform for the deployment of mobile Smart Card applications.

This development solution allows the creation of applications utilising:

• Smart Cards
  • SIM cards
  • Memory cards
  • Secure cards
• IR Comms
• Graphical LCD Display
• Keypad data entry
• Serial Memory
• Sound.

The unit is fully programmable and contains one of the latest 18F type PICmicro™ microcontrollers, offering a massive 32K of code space and a huge 1500 bytes of RAM. User interactivity is via a 16 key membrane keypad, and a 128 x 64 graphics LCD that can display both TrueType fonts and Graphics simultaneously ( including moving Graphics. Additional data storage is also catered for by the use of internal 8K bytes I²C serial eeprom, which can be expanded to 256K bytes

The unit is equipped with a standard IS07813 Smartcard socket and an internal mini SIM (GSM style) socket, IR is an option. (requires a TxRx device to be fitted), PCB pads and IR window are fitted as standard.

A 40 page booklet accompanies the PROTON ChipDrive Mobile outlining its internal circuitry, and offers many code examples written in the easily understood yet powerful language of PROTON+ PICBASIC.

In addition this package includes the very popular ChipDrive Development pack for the PC, containing:

• source code examples for the PC in:
  • VB
  • Delphi
  • C
• ChipDrive Micro
• CardServerAPI and PC/SC support

Programming the unit is accomplished by a simple serial interface and bootloader, allowing the PIC program to be transferred to the CDM in seconds via a smart card, or direct ‘device’ programming of the socketed PLCC PICmicro™.

Shown below are some of the PROTON ChipDrive Mobile’s features.

The Lite edition of the Proton Development Suite is a special version of our fully-fledged Proton Development Suite. As a standalone product, the Lite Edition is a free and fully functional, non-expiring download which includes the Compiler, the IDE and the ISIS Simulator. Of course, because it’s a Lite Edition, there are some limitations over the Full Edition — The Lite Edition supports the following devices:

·         PIC12C508: The 8-pin, 12-bit 12C508 device is arguably the best-selling microcontroller of all-time, but has now been superceded by the 14-bit 12Fxxx range.

·         PIC12F675: The 8-pin, 14-bit 12F675 is one of the new breed of PICmicros® that incorporates advantages such as ADC, comparators, on-chip EEPROM and of course Flash re-programmability.

·         PIC16F628A: The 18-pin, 14-bit 16F628A is the sucessor to the ever popular, but now very outdated, 16F84 device. The 16F628A offers 2KBytes of code space, 128Bytes of RAM, on-chipEEPROM, comparators, USART and hardware PWM.

·         PIC16F877: The 40-pin, 14-bit 16F877 is the Rolls-Royce of the 14-bit core devices and contains 8KBytes of code space, 368Bytes of RAM, 256Bytes of on-chip EEPROM and more on-chip features than you can shake a stick at - such a USART, HPWM, etc, and is the obvious choice for any new design.

The Lite Edition also has a restriction of 50 lines of valid BASIC code. This does not include; comments, lines containing only a label, or empty lines. This, we hope, should be enough to give you a feel of just how powerful the Development Suite really is!Because of the 50 line limit, the INCLUDE directive has also been disabled.The choice of crystal frequencies is also limited to 4MHz and 20MHz, as opposed to 3.58MHz, 4MHz, 8MHz, 10MHz, 12MHz, 14.32MHz, 16MHz, 20MHz, 24MHz, 32MHz and 40MHz available with the Full Retail version of the Proton Development Suite.The Lite Edition download also contains the full Proton Development Suite’s manual in PDFformat.
