MSP430L092: Programming the MSP430l092 Chip

Part Number: MSP430L092
Other Parts Discussed in Thread: MSP-FET

I have investigated to program MSP430L092 microcontroller. I found that it requires MSP-TS430L092 target board for downloading code because it doesn't have non-volatile memory (EEPROM) so I am curious that after I program the chip with MSP-FET Flash Emulation Tool, target board and IAR EMBEDDED software, Can I plug out msp430l092 pin connections from target board? I mean that does my code work inside msp430l092 without target board independently?

    The msp430l092 contains no user programmable non-volatile memory. The target board contains an EEPROM to store the program and a boost-converter circuit to allow the ROM based boot loader in the msp430l092 to transfer the program in external EEPROM into RAM in the msp430l092 at reset.

    So, no the msp430l092 won't work without the EEPROM and boost-converter circuity on the target board.

    [The MSP430C091/C092 contain a mask programmed ROM which allow the MSP430C091/C092 to be used standalone without the external EEPROM but the MSP430C091/C092 are only intended for mass production runs of 100000+ devices - presumably due to the cost of setting up a mask programmed ROM]

  • I intend to work with target board because of EEPROM. How can I retake my code from EEPROM into MSP430l092 ram without IAR embedded application after I restart my microcontroller? When I restart MSP430l092 , it loses my code but I believe that EEPROM should have my code but I couldn't retake my code. How can I do this ? I consider that it would be related with P1.2 but I am not sure. Can you help me please?

    Have you followed the steps in section 3.3.2 RAM/External SPI Memory Download Option in IAR of MSP430L092 Development Guide (Rev. A) - Texas Instruments to cause the program to be downloaded by IAR into the EEPROM?

    i.e. are the External code download and Fill unused code memory checkboxes ticked?
