This application note describes the three methods that can be used to program the Flash code memory of the 89C51Rx+/Rx2/66x families of microcontrollers. It discusses in detail the operation of the In-System Programming (ISP) capability which allows these microcontrollers to be programmed while mounted in the end product. These microcontrollers also have an In-Application Programming (IAP) capability which allows them to be programmed under FirmwARe control of the embedded application. This capability is also described

The W78E58B is an 8-bit microcontroller which has an in-system programmable Flash EPROM for FirmwARe updating. The instruction set of the W78E58B is fully compatible with the standard 8052. The W78E58B contains a 32K bytes of main ROM and a 4K bytes of auxiliary ROM which allows the contents of the 32KB main ROM to be updated by the loader program located at the 4KB auxiliary ROM 512 bytes of on-chip RAM four 8-bit bi-directional and bit-addressable I/O ports an additional 4- bit port P4 three 16-bit timer/counters a serial port. These peripherals are supported by a eight sources two-level interrupt capability. To facilitate programming and verification, the ROM inside the W78E58B allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security

The SL11RIDE is a low cost, high speed Universal Serial Bus RISC based Controller board. It contains a 16-bit RISC processor with built in SL11RIDE ROM to greatly reduce FirmwARe development efforts. Its serial flash EEPROM interface offers low cost storage for USB device configuration and customer product specific functions. New functions can be programmed into the I2C by downloading it from a USB Host PC. This unique architecture provides the ability to upgrade products, in the field, without changing the peripheral hardware.

Wishbone to LPC (Low-Pin Count) Bridge, includes master and slave modules. Supports 8-bit I/O Read and Write cycles, 8-bit Memory Read/Write cycles, DMA cycles, and up to 32-bit FirmwARe memory read/write cycles. Serial IRQ support is also provided. None of this has been tested (yet) with a third-party LPC Peripheral or Host.

userial is an Free project building an USB to I2C/SPI/GPIO bridge, using the Atmel AT90USB647 chip. Hardware and Software are released under an Open Source licence. It supports the following interfaces: * USB interface (serial emulation) * JTAG * I2C (TWI) * SPI * 8 General purpose digital I/O * 4 Analog to Digital converters (currently no FirmwARe support)

Among the many features built into Microchip’sEnhanced FLASH Microcontroller devices is the capability of the program memory to self-program. This very useful feature has been deliberately included to give the user the ability to perform bootloading operations.Devices like the PIC18F452 are designed with a designated“boot block”, a small section of protectable program memory allocated specifically for bootload FirmwARe.

Обратите внимание на обновление с версии 3.x до 4.x прошивку USBDM Это изменение осложненной в Существование Bootloader в настоящий в БДМ FirmwARe. Если не заменило этот загрузчик будет продолжать использовать в оригинале VID / ПИД - регулятора. Из - за этого, желательно , чтобы полностью заменить на The на БДМ встроенного программного обеспечения. Годов для JS16 на основе BDMS это Простой процесс эксплуатации так как при на Freescale JS12 Bootloader Программное обеспечение может быть использовано для замены всех на прошивке. См постройки и установке . основе для JMxx в BDMS необходимо использовать HCS08 программист перепрограммировать на все устройство таким образом , что при загрузчик Обновленный когда в микропрограммы изменен И.С. Rest. в Если не программист тогда это доступные еще возможно к БДМ при обновлении встроенного программного обеспечения А , используя в The Bootloader Но при Bootloader будет оставаться неизменным.Для этого необходимо будет установить драйверы дважды - один раз для старого VID / PID используется загрузчиком и снова для нового VID / PID используется основной прошивкой Doing так будет оказывать какие-либо драйверы OSBDM неоперабельных на этом USB-порт. ,
