The CAT93C46 is a 1 kb Serial EEPROM memory device which isconfigured as either 64 registers of 16 bits (ORG pin at VCC) or 128registers of 8 bits (ORG pin at GND). Each register can be written (orread) serially by using the DI (or DO) pin. The CAT93C46 features aself−timed internal write with auto−clear. On−chip Power−On Resetcircuit protects the internal logic against powering up in the wrongstate.

The bootloader is stored in the internal boot ROM memory (system memory) of STM32devices. It is programmed by ST during production. Its main task is to download theapplication program to the internal Flash memory through one of the available serialperipherals (USART, CAN, USB, etc.). A communication protocol is defined for each serialinterface, with a compatible command set and sequences

要搞清楚單片機與PLC的異同，首先得明確什幺是單片機，什幺是PLC。對此，我們簡要回顧一下計算機的發(fā)展歷程也許有幫助，按計算機專家的原始定義，計算機系統(tǒng)由五大部分--即控制單元（CU）、算術運算單元（ALU）、存儲器（Memory）、輸入設備（Input）、輸出設備（Output）組成。早期計算機（晶體管的或集成電路的，不包括電子管的）的CU或ALU由一塊甚至多塊電路板組成，CU和ALU是分離的，隨著集成度的提高，CU和ALU合在一塊就組成了中央處理單元（CPU）,接著將CPU集成到單塊集成電路中就產(chǎn)生MPU或MCU,出現(xiàn)了如Intel4004、8008、8080，8085、8086、8088、Z80等MPU。此后，MPU的發(fā)展產(chǎn)生了兩條分支，一支往高性能、高速度、大容量方向發(fā)展，典型芯片如：Intel80186、286、386、486、586、P2、P3、P4等，速度從4.7MHz到現(xiàn)在的3.2GHz。另一支則往多功能方向發(fā)展，將存儲器(ROM、PROM、EPROM、EEPROM、FLASHROM、SRAM等)、輸入/出接口（Timer/Counter、PWM、ADC/DAC、UART、IIC、SPI、RTC、PCA、FPGA等）全部集成在一塊集成電路中而成為SOC。依愚之見，這就是當今廣泛應用的單片計算機，簡稱單片機。這一分支可謂品種繁多，位寬從8位到32位，引腳數(shù)從6個到幾百個，工作頻率從幾十KHz到幾百MHz,體系結構既有CISC也有RISC,數(shù)不勝數(shù)。常用的有MCS-51系列、MCS-96系列、PIC系列、AVR系列、ARM7/9系列、TMS320系列、MSP430系列、MOTOROLA眾多的單片機等等。

The MSP-FET430U14 is a powerful flash emulation tool to quickly begin application development on the MSP430 MCU. It includes USB debugging interface used to program and debug the MSP430 in-system through the JTAG interface or the pin saving Spy Bi-Wire (2-wire JTAG) protocol. The flash memory can be erased and programmed in seconds with only a few keystrokes, and since the MSP430 flash is ultra-low power, no external power supply is required. The debugging tool interfaces the MSP430 to the included integrated software environment and includes code to start your design immediately. The MSP-FET430UIF development tools supports development with all MSP430 flash devices

NXP Semiconductor designed the LPC2400 microcontrollers around a 16-bit/32-bitARM7TDMI-S CPU core with real-time debug interfaces that include both JTAG andembedded Trace. The LPC2400 microcontrollers have 512 kB of on-chip high-speedFlash memory. This Flash memory includes a special 128-bit wide memory interface andaccelerator architecture that enables the CPU to execute sequential instructions fromFlash memory at the maximum 72 MHz system clock rate. This feature is available onlyon the LPC2000 ARM Microcontroller family of products. The LPC2400 can execute both32-bit ARM and 16-bit Thumb instructions. Support for the two Instruction Sets meansEngineers can choose to optimize their application for either performance or code size atthe sub-routine level. When the core executes instructions in Thumb state it can reducecode size by more than 30 % with only a small loss in performance while executinginstructions in ARM state maximizes core performance.

PICKIT™ 2 PROGRAMMER-TO-GO USER GUIDE The PICkit 2 Programmer-To-Go functionality allows a PIC MCU memory image to be downloaded into the PICkit 2 unit for later programming into a specific PIC MCU. No software or PC is required to program devices once the PICkit 2 unit is set up for Programming-To-Go. A USB power source for the PICkit 2 is all that is needed.
