I just saw this little microprocessor. You guys building EFI controllers
might like some of it's capabilities.
32-bit powertrain flash MCU employs 90-nm process
Microcontroller achieves 200-MHz speed and operation up to 125C
Said to be the industry's first 90-nm-process microcontroller with on-chip
flash memory, the 200-MHz SH72546RFCC gains a fourfold speed increase over
its predecessors and features flash memory capacity of 3.75 Mbytesamong the
largest available. The device operates at -40 to 125?C and is optimized for
control systems for automobile engines, transmissions, and other systems
that require real-time control.
The chip's superscalar design has a double-precision floating-point unit and
a cache unit that allows single-cycle access to the flash. The chip has a
multifunction timer unit with up to 106 outputs, dual multichannel DMA
controllers, an interrupt controller, and a 37-channel 12-bit A/D converter,
as well as CAN, SCI, and SPI interfaces.
The IC is a preproduction device offering features to aid software design
and debug. The 272-pin PBGA-packaged IC is the basis for an upcoming
lower-cost mass-production product family that will have performance,
package, and pin arrangement compatibility. Engineers performing system
development using the SH72546RFCC will be able to make a speedy and seamless
transition to lower-cost mass-production devices. ($980available October.)

Do you think there are enough A/D channels?
