LPC2292FBD144/01.5 is not recommended for new design

Hi 

LPC2292FBD144/01.5 is not recommended for new design.

1. Can you suggest alternate pin to pin replacement with more code memory ?

2. Can you also suggest alternate microcontroller of similar family with added feature and more code memory?

HI vikhyatbaxi 

We have pin to pin replacement LPC177x/8x for LPC23xx and LPC24xx but not replacement for LPC21xx/22xx.

If you want, please send me your requirement. Flash/RAM size, CPU frequency, necessary peripherals needed. I can help you look for a replacement. but please note, not pin to pin replacement.

Thanks,

Jun Zhang

Hi 

It is running production design changes, thus

Option1 :

We would like to keep Micro family similar if we can not find pin-pin replacement, micro frequency similar

1. Family : ARM7 same as LPC2292FBD144/01.5

2.Core Size : 32bit same as LPC2292FBD144/01.5

3. Speed : 60MHz  same as LPC2292FBD144/01.5

4. Connectivity : > = 1 CANbus, EBI/EMI, >=1 I²C, Microwire, >=1 SPI, SSI, SSP, >=1 UART/USAR

5. Peripherals : POR, PWM, WDT

6. No of IO >= 112

7. Program memory >= twice the current memory 256KB (256K x FLASH

8. RAM size >= twice the current size 16K x 8

9. A/D >= 8x10b i.e 12-bit preferred.

Option2 : New micro family with above minimum requirement which will require significant amount of work and as it is running production change we may not proceed with option2.

HI

Thanks, please check LPC546xx. it may match your requirement. It is function replacement but not pin-to-pin replacement.

If this can't help, please let me know.
