Texas Instruments MSP430F449
Benefits of the MAXQ2000-RAX over the MSP430F449:
- 64KB flash and 2KB RAM, which enables larger, more complex applications, vs. 60KB flash and 512B RAM for the MSP430F449
- Clock rate of 20MHz approaches 20 MIPS, vs. 16 MIPS for the MSP430F449
- Hardware Multiplier can multiply-and-accumulate in 1 clock cycle (3X faster), vs. multiply-and-accumulate in 3 clock cycles for the MSP430F449
- Hardware Multiplier has a 40-bit accumulator to perform more complex math, vs. a 32-bit accumulator with the MSP430F449
- LCD controller with a separate module to perform the timing for the commons and segments, vs. using one of the timers (BASIC TIMER 1) to generate timing for the commons and segments for the MSP430F449
- Internal adjustable resistor allow contrast control without external components, vs. the need for external components to allow contrast control for the MSP430F449
- Internal voltage-divider resistors eliminate external components, vs. the need for external voltage-divider resistors for the MSP430F449
- Separate modules for SPI and USART, so both peripherals can be utilized, vs. multiplexed USART and SPI for the MSP430F449
- Separate I/O supply for optimum flexibility, vs. separate I/O supply for the MSP430F449
Benefits of the MSP430F449 over the MAXQ2000-RAX:
- MSP430F449 has brownout detect and SVS
- MSP430F449 offers comparator and ADC
- MSP430F449 has 160-segment display vs. 100/132 segments for MAXQ part
- MSP430F449 has 0.1mA stop mode vs. a 0.7mA stop mode for MAXQ
