This application note describes how an AVR with the Store Program Memory (SPM) instruction can be configured for Self-programming. The sample application communicates via the UART with a PC running the AVR Open Source Programmer (AVROSP) from Application note AVR911. This enables Flash and EEPROM programming without the need for an external programmer. The code is also compatible with AVRProg (only for devices supported by AVRProg). A Boot Loader program is placed inside the Boot Section of the Flash memory. This program handles communication with the host PC, and facilitates programming of both Flash and EEPROM. Once programmed, different levels of protection can be individually applied to both the boot and application portion of the Flash memory. The AVR thus offers a unique flexibility, allowing the user extensive degrees of memory protection. Products & Services
Device programmers are used to program nonvolatile memory such as microcontrollers, erasable programmable read-only memory (EPROM), programmable logic devices (PLDs), programmable array logic (PAL), generic array logic (GAL) and other electrically programmable devices.
Device programming services companies program FPGAs, ASICs, GALs, PALs, EPROMs and other electronic components. Sometimes, this programming is performed at facilities that assemble PCBs.
Programming adapters are designed to convert the pin-out of one integrated circuit (IC) package into another. They provide a socket for various IC package types and plug into a device programmer or prototype board.
Flash memory cards provide electrically erasable, programmable, read-only memory (EEPROM) that can be erased and reprogrammed in blocks instead of one byte at a time.
Specialty memory chips are specialty or proprietary products and accessories related to memory chips.
