Hi Gurus, I am switching from AVR to ARM. Currently, I use an ATmega162 which is running out of code space (16kB) and performance. But I find it difficult to choose between Atmel's ARM (looking at the SAM7S series) and thePhilips LPC2104/5/6 series. I don't need many peripherals (yet). My current design uses an FTDI chip for USB, I could save that by using Atmel (Philips has no USB), but o...

How can I use JTAG mode without ETM port on Philips LPC 210x? I pull up DBGSEL and RTCK during RESET, processor starts using jtag but also ETM port is enabled (I can`t use ETM pins as GPIO). I am also using LPC 212x - it is posible to turn on jtag without ETM port. Thank You

Hi, I'm just wondering if anybody has had any problems with the Philips PCF8563 RTC. I've devised a simple unit test which does the following: 1. RTC seconds, minutes and hours registers are initialised to zero. 2. Continuously samples the RTC (at 1 millisecond) and reads the seconds, minutes and hours registers 3. Each register has an associated counter in software, which is incremente...
Extract program from old mask-ROM 80C51?

I have a mask ROM 80C51 in an old computer, made 1992. The top of the 44 pin PLCC says: Philips logo 0290,031-01 WP J399 223380 DfD9240V6 YU (R) (C) INTEL 1980 (R) PHILIPS 1989 The schematic tells me it's an 80C51, but no other part numbers. 0290,031-01 is the customer's (Acorn's) part number. I don't know what sort of 8051 it is inside. The clock line XTAL1 is driven directly fr...

Hi, I am using the Philips PDIUSBD12. I am polling the device since I cannot use the interrupt pin. The part seems to work most of the time though it occassionally gives bad IN packets during enumeration. I also can only poll the interrupt register once after enumeration to see if I am getting an OUT packet. If I poll the interrupt register after enumeration then I start sending bad or inv...

Hello, I am about to use a P89c669 in a design with external program memory. Problem is that the manual states that EA pin either disables external program memory when held HIGH, or disables internal flash when EA is held LOW. The feedback I got from Philips is that when EA is held HIGH (???) both external and internal memory can be used in a mixed mode. So the big question is, if I wan...

We'd like to use the Philips LPC2114 in a new design (we need 8 capture channels, a serial port etc.), but all the dealers say the lead time is 24 weeks. We can't possibly wait this long to have a pilot series manufactured. Is there any place where we could buy, say 50 of these MCU's _now_ or do we need to use some other chip? I would consider using the new Atmel AT91SAM... chips, but the...
