Hi

 

I'm making a research for a project starting next month and i'm looking for some opinions before making decisions, since we've never used freescales before

 

my particular assigment involves

16ch ATD

RS232

Modbus

CAN

2 SPI

external memory

real time clock

characters LCD

buttons, maybe 4

some LEDs and miscelaneous ON/OFF

5V supply

low voltage detect

(L)QFP

COP watchdog

clock monitor

80 pins are ok, 144 is a bit of an overkill but i wont complain. 

 

if i get PWM, input capture / output compare / counter / event counter, freaking great.

 

this is how i ran into the S12K, has

16 ATD

2 SCI to place my 232 and modbus

2 CAN

3 SPI, 1 to hang a micro SD card socket and the real time clock, 1 to communicate with other devices, 1 bonus

- dont know yet what to do with the LCD - 

bonus PWM, timer module  and IIC

and meets all other requirements

 

 

 

so, how much of a bad idea is this arrengement? advices, ayone? does anyone knows of a more suitable micro to do the magic? i've seen micros with LCD drivers and/or external memory drivers, but i'm reaaaaally interested on the character LCD and the micro SD card. What can i do with the LCD?

 

someone suggested the K60 but, adding such "complex" graphics antics to our proyect will just rise the price out of competition worthlessly: people shouldn't be around our product under normal circumnstances anyways, just for emergency or maintenance.

 

USB and Ethernet were considered, but they are more of a fun plus than an actual need

 

well, i'm open for suggestions. thanks in advance.
