5 / 52 page STR73xFxx Overview 5/52 2 Overview Package choice: reduced pin-count TQFP100 or feature-rich 144-pin TQFP or LFBGA The STR73xF family is available in 3 packages. The TQFP144 and LFBGA144 versions have the full set of all features. The 100-pin version has fewer timers, I/Os and ADC channels. Refer to the Device Summary on Page 1 for a comparison of the I/Os available on each package. The family includes versions with and without CAN. High speed Flash memory The Flash program memory is organized in 32-bit wide memory cells which can be used for storing both code and data constants. It is accessed by CPU with zero wait states @ 36 MHz. The STR7 embedded Flash memory can be programmed using in-circuit programming or in-application programming. The Flash memory endurance is 10K write/erase cycles and the data retention is 20 years @ 85° C. IAP (in-application programming): IAP is the ability to re-program the Flash memory of a microcontroller while the user program is running. ICP (in-circuit programming): ICP is the ability to program the Flash memory of a microcontroller using JTAG protocol while the device is mounted on the user application board. The Flash memory can be protected against different types of unwanted access (read/write/erase). There are two types of protection: ● Sector write protection ● Flash debug protection (locks JTAG access) Flexible power management To minimize power consumption, you can program the STR73xF to switch to SLOW, WFI LPWFI, STOP or HALT modes depending on the current system activity in the application.
