The 32-bit ARM-based STR710F microcontroller family suits cost-sensitive applications. These 50-MHz devices include the USB-based STR711 and CAN-base (controller-area network) STR712. Chips are available with 64 to 256 kbytes of flash memory, 16 kbytes of data flash, and 16 kbytes of RAM. The chip includes communication and general-purpose I/O interfaces along with Multimedia Card (MMC) and Smart Card interfaces. Prcing for the STR710F series starts at $4.60 in low-pin-count TQFP64 and 144-pin TQFP144 packages.
