MCU with CANbus + 10-bit ADC

Hi,

Which is the cheapest MCU that you know of, with
(Flash) AND (CANbus) AND (10-bit ADC) AND (EEPROM OR I2C)?

Is there any web page with a database where I can look for an MCU with
a certain set of characteristics? It should cover as many
manufacturers as possible.

Thanks in advance,

PIC18F2480, around $5 for single quantities.

Try digikey's webpage and search for "Microcontrollers".
They have a parametric search.

I haven't seen any cheap CAN uCs. Cheapest solution I can think of
would be your choice of uC that has SPI and a Microchip MCP2515. In
single quantities you can get a MCP2515 for $3 and an Atmel ATMEGA48
for $2.50. Obviously in larger quantities price will decrease
substantially. Cheapest part with CAN integrated into it that I know of
is the Microchip PIC18F2480 at about $10 in single quantities.

Cheap normally means low pin count, and low code size.

Atmel do  89C51CCxx series, from 16K to 64K, in 24/28/32/44/64 pins,
and also their AT90CANxx series, but those only in 64 pin.

Infineon have many CAN choices, the XC8xx family.

Philips are thin in Flash+CAN on 8 bit, but their LPC2xx family have
CAN in the larger members.

Where are you seeing this price? Digi-Key lists the cheapest PIC18F2480
for $9.73.

Well,

you can use an 8-bit PIC or a 32-bit ARM7 device for the same price.
The LPC2119 at Digikey is $9.50 with 128k Flash, 16k SRAM, 10-bit ADC
and runs up to 60 MHz.

a Freescale 9S12C32 is "cheap".

There might be also cheaper 9S08 or newer HC908 derivatives with 10
bit ADC.

TI has ARM7TDMI core devices with CAN for similar prices ($5/1K). Most
of these devices will require you to use an external SPI or I2C
SEEPROM, if you want true EEPROM which you can erase one byte at a
time.

Microchip Direct -- $5.76. Mouser has the
PIC18F248 for $5.99.

This press release

http://www.eeproductcenter.com/micro/brief/showArticle.jhtml?articleID=180204117

mentions "the XC886/888 goes for about $2.68"  /10K
so you'll need to enquire for a more exact price, as not all XC886 
family members have CAN enabled.
