Other Parts Discussed in Thread: MSP430F147 , MAX202 We have several hundreds of device incorporating MSP430F147/148/149 running.
Recently, we started experiencing failures in UART1 Rx pin (URXD1). This pin is driven by a logic gate powered by the same…
I just looked into the MAX3222 datasheet.
Patrick8918 said: I use 5 capacitors , C1 = .2uF, C2-C4 = 1uF, and then also use a .1uF on at Vcc.
hmmm, the datasheet talks about 5 times 0.1µ @3.0..3.6V. 1µF is probably too much for the charge pump…
The guide has reached revision H, mine was F (only 6 weeks old!).
Hmmm, a really complex circuit. It has the advantage of powering the MSP from PC port, but usually, the MSP already has a power supply of some sort, and if the MSPs supply is for less…
