Development of MSP430 microcontroller
TI in 1996 to early 2000, has introduced several 31x, 32x, 33x series, the series of LCD driver module, to improve the integration of the system better. Each of a series of ROM (C), OTP (P), and EPROM (E) chip. EPROM is expensive, environment temperature range is narrow, mainly used for prototype development. It also shows that the series of development mode, namely: users can develop prototype with EPROM type; OTP type for small batch production; ROM type is suitable for batch production of the product.
The 2000 launch of the 11x/11x1 series. This series uses the 20 pin package, memory capacity, on-chip less functions and I/O pin count, but relatively low prices.
This time MSP430 has revealed a series of technical characteristics of its low power consumption, but there are not just as one wishes. Many important properties of it such as: on-chip serial communication interface, hardware multiplier, enough I/O pins, 33x series have only. 33x series of high prices, more suitable for the application of more complex systems. When the user design needs more consideration of cost, 33x is not necessarily the most suitable. And the on-chip high precision A/D converter and 32x series is only.
In 2000 July launched F13x/F14x series, in 2001 July to 2002 also launched F41x, F43x, F44x. These are all Flash type mcu.
F41x Series MCU with 48 I/O, 96 LCD drive. F43x, F44x series is based on 13X, 14x, increase the LCD driver, the driver LCD segments by 3xx series of up to 120 to 160. And adjust the display memory in the memory area address, to expand the space for future development.
Part of the product MSP430 series with Flash memory, all showed significant advantages in system design, development and application. TI launched its Flash memory and JTAG boundary scan technology of cheap development tools MSP-FET430X110, will be the international advanced JTAG technology and Flash online programming technique based on MSP430. The Flash technology and FET development tools development mode, has the advantages of convenient, cheap, practical, provides an ideal prototype development approach to the user.
In 2001 the company TI also announced the BOOTSTRAP LOADER technology, it can be used in the later blown fuse as long as a few lines can be changed and the operation of the internal program. Provides a convenient means for the upgrade of system software. BOOTSTRAP has a high degree of security, the password can be up to 32 bytes in length.
TI company during late 2002 and 2003 also rolled out F15x and F16x series products. In this new series, with the development of the two aspects of. One is from the memory, RAM can increase the capacity, such as the F1611 RAM capacity increased to 10KB. Two from the peripheral module, increased I2C, DMA, DAC12 and SVS modules.
