Hi, On LPC2103, Can I short VBat to V18? The 2 pins are next to each other. => Simplify my PCB layout => Simplify my RTC backup circuit also, if V18 does not take too much current when power down. Single micropower 1.8V LDO used. Vbat requires 3.3V for normal Operation. I do not fully understand the datasheet, does VBat work from 2.0V to 3.6V any time from chip operation to batter

Hi everyone! I am using LPC2103 in my project. LPC is connected to server using RS485 interface (Semi-duplex). Also I have EEPROM memory connected to LPC. I would like to do this if it is possible: 1. Using my resident LPC firmware, load new firmware to EEPROM memory. 2.

Hi I see when shorting Vbat to ground the CPU stops running. So i assume the CPU will also stop when there is an empty battery connected. The datasheet only has this note : [4] The RTC typically fails when VBAT drops below 1.6 V. So i think this does not mean the CPU itself should stop when vbat is too low. Are there any issues with this ? Johan

I was thinking of getting some PCBs made for a little 24 pin module using the LPC2103. The proposed schematic is module.pdf in the Files section. Of course, I've had to dispense with some of the I/Os, and JTAG connection is via the pins. Many applications don't need all the available I/O that is provided on the 40 pin modules, and small size and low cost might be more important. I'm open to

Hello all: I'm a developer of 8 bit microcontrollers applications that wants to switch to ARM. So I'm learning my own all this stuff, and as a newbee, I have some problems. Probably the most stupid ones. I have a Macraigor Wiggler clone made by myself, and a development board with an LPC2103, also made by myself. I've checked all circuitry and it seems to be OK. I use the IAR KickStar

Hi, I use the LPC2103 microprocessor and I like it very much. I was wondering if the usage of barrel shifter in the ARM instruction set eats up more cycles. ARM datasheets mention the SHIFT(Rs) eats up one more cycle, though I'm not sure if they mean that shifting by a register takes a cycle, but shifting by a const is free, or any shift takes a cycle.
