This datasheet also covers the CY9B520M variant, as both devices belong to the same 32-bit fm3 microcontroller family and are provided as variant models within a single manufacturer datasheet.
Key Features
32-bit Arm® Cortex®-M3 Core.
Processor version: r2p1.
Up to 72 MHz Frequency Operation.
Integrated Nested Vectored Interrupt Controller (NVIC): 1 NMI (non-maskable interrupt) and 48 peripheral interrupts and 16 priority levels.
24-bit System timer (Sys Tick): System timer for OS task management
On-chip Memories
[Flash memory].
Dual operation Flash memory Dual Operation Flash memory has the upper bank and the lower bank. So, this series could implement erase, write and read.

32-bit microcontrollers dedicated for embedded controllers with low-power consumption mode and competitive cost. These series are based on the Arm® Cortex®-M3 Processor with on-chip Flash memory and SRAM, and have peripheral functions such as various timers, ADCs, DACs and Communication Interfaces (USB, CAN, UART, CSIO, I2C, LIN). The products which are described in this data sheet are placed into TYPE9 product categories in “FM3 Family Peripheral Manual”.
