I want to use the LPC2210 with an external page mode flash S29GL032. The LPC2210 has to boot from this device so the value of the BOOT0 and BOOT1 pins is important (P2.26 and P2.27). Page 93 of the user manual (Rev. 01) contains the description for PINSEL2[5:4]. The table shows me that BOOT1 should be 0 and BOOT1 should be 1 to have access to OE, D15:0 an

I'm trying to calculate how many MIPS I could get out of a LPC2210 running at highest possible frequency using external burst mode flash memory. Somehow, I'm a bit disappointed at the moment. 1? On page 31 of the LPC2210 2220 User Manual is stated that the length of of a read access (except for subsequent reads from a burst ROM), in CCLK cycles, is the number of waitstates + 3. If I'm


Connecting big endian device to LPC2210

Hi, I'm in the process of connecting a EPSON S1D13A05 display controller to the LPC2210. The 16-bit S1D13A05 will operate in big endian mode (the only mode available without external ready signal) but the LPC2210 is litte endian (thanks to Micron Engineering for pointing this out). Will a hardware byte-swap solve all "endian" problems (LP

Hello, I'm evaluating the use of LPC2210 for our development. One thing I couldn't get from the data sheet, is whether the LPC2210 could run out of RAM. Does Anyone know if there are any issues such as vector table relocation restriction or any other issues? In the past, I have used an MMU (on other Processors) to remap address 0 to another physical

Hello Helpful LPC2000 people. I am using an LPC2210 for my application. Right now, we are trying to make a prototype board and i have come to a snag. We are using 32 Mbit external flash memory, on a 16-bit interface. We are also using 16 Mbit external RAM. The LPC2210 datasheet mentions: > BOOT1 - While RESET is LOW, together with BOOT0 > controls booting and internal operation. Inter

Hello all, a hardware related question: the LPC2210 has a dual power supply: 1.8V core voltage and 3.3V for the I/O. Is the power-on (and power-off) sequence of these 2 voltages critical? Will a 1.8V regulator behind the 3.3V regulator do the job? The 1.8V will be a little bit later during power-on. We bought a development board from Phytec a

Hi For controlling an RGB OLED (2.4") i need something with external ram (1MByte) and some external Flash (512KB) any hint on what RAM (ISSI?) and FLASH (AMD ?) devices to use. The LPC2210 seems to be the cheapest with external bus. I think the 1Mbyte should be enough to do some graphic calculations (frame buffer ) Thanks Johan ------------------------------------
