ST STM32H7B3I-EVAL User Manual

8.6 OCSPI NOR Flash 2 module (MB1242)
8.6.1 Description
CN11 (left) and CN10 (right) allow connecting MB1242 modules. Different versions of this module support ICs part
numbers described in Table 54 and Table 55. These connectors are connected to OCSPI2 interface of
STM32H7B3LIH6QU on the STM32H7B3I-EVAL Evaluation board.
WARNING: Due to board design, as OCSPI2 interface is “shared” with SDRAM and camera, it can only be tested
at low speed (Maximum: 50 MHz).
