The STM32F769/779 lines offer the performance of the Cortex-M7 core (with double precision floating point unit) running up to 216 MHz while reaching similar lower static power consumption (Stop mode) versus the STM32F427/429/437/439 lines.
The STM32F779 line integrates a crypto/hash processor providing hardware acceleration for AES-128, -192 and -256 encryption, with support for GCM and CCM, Triple DES, and hash (MD5, SHA-1 and SHA-2) algorithms.
The STM32F769 and STM32F779 portfolio provides from 1Mbyte to 2 Mbyte of Flash memory, 512-Kbyte SRAM including up to 128 Kbytes of Tightly-Coupled Memory for Data (DTCM), 16-Kbyte ITCM RAM, 4-Kbyte Backup RAM and 100- to 216-pin packages including a WLCSP* form factor as small as 5.6 x 6.1 mm.
Note: * while the “regulator off” feature is available in the STM32F7x9 LQFP and BGA package variants upon activation via a dedicated input, the feature is not available on standard WLCSP product variants. However, two specific WLCSP “regulator off” devices are available, STM32F778 (with crypto/hash accelerator) and STM32F768 (without crypto/hash accelerator), operating at 180 MHz maximum CPU frequency.
