SOC System-on-chip 32-bit ARM® Cortex®-M3 FM3 Microcontroller chip CY9BF121JPMC-G-JNE2

The MB9B120J Series are highly integrated 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 and Communication Interfaces (UART, CSIO, I2C, LIN).
The products which are described in this data sheet are placed into TYPE10 product categories in FM3 Family Peripheral Manual.
