Cypress’s FM3 is a portfolio of 32-bit, general-purpose and highly-integrated MCU's based on the Arm® Cortex®-M3 processor. The FM3 portfolio contains a wide range of products and is categorized into four groups: “HIGH PERFORMANCE”, “BASIC”, “LOW POWER” and “ULTRA LOW LEAKAGE.” All products are software-compatible because of their common SoC design with the same peripherals and CPU architecture. Users can select from different CPU speeds, memory size, supply voltage and package options.
The FM3 portfolio offers CPU speeds of up to 144 MHz and operating voltages ranging from 1.65V to 5.5V. The devices incorporate up to 1.5 MB of flash and up to 192 KB RAM. The fast flash memory combined with a flash accelerator circuit (pre-fetch buffer plus instruction cache) provides zero-wait-state operation of up to 144 MHz. Integrated peripherals such as multiple motor-control timers, high-speed ADCs and a variety of communication interfaces are available. Package options include LQFP, QFN and BGA, with pin counts ranging from 32 to 192 pins.
The FM3 portfolio unleashes your product design with a wide range of product options offering operating frequencies up to 144MHz, 1.65V to 5.5V operating voltage, and up to 1.5MB flash and 192KB RAM. The fast flash memory combined with a flash accelerator circuit (pre-fetch buffer plus instruction cache) provides zero-wait-state operation up to 144MHz.
5.5V power supply capability maximizes noise immunity for industrial and motor control applications. The internal, trimmed RC oscillators function as an independent clock source for the clock supervisor and watchdog modules. The devices also feature a two-stage programmable Low Voltage Detector (LVD), a CRC hardware module, a Memory Protection Unit (MPU), and programmable emergency stop input for inverter motor control.
Peripheral features include multiple motor-control timers, high-speed 12bit ADCs, and a variety of communication interfaces. Available packages, which range from 32 to 176 pins, include LQFP, QFN, and BGA types.
