Embedded Microcontroller)
The FT90x series includes the FT900, FT901,
FT902 and FT903 which are complete System-
On-Chip 32-bit RISC microcontrollers for
embedded applications featuring a high level
of integration and low power consumption. It
has the following features:
High performance, low power 32-bit FT32 core
processor, running at a frequency of 100MHz.
256kB on-chip Flash memory.
256kB on-chip shadow program memory.
True Zero Wait States (0WS) up to 3.1 DMIPS
per MHz performance
64kB on-chip data memory.
EFUSE for security configuration.
Integrated Phase-Locked Loop (PLL) supports
external 12MHz crystal and direct external clock
source input.
32.768 kHz real time clock support.
One USB2.0 EHCI compatible host controller
supports high-speed (480 Mbit/s), full-speed

IEEE 802.3/802.3u standards. (FT900 and
FT901 only)
Supports One-Wire debugger for downloading
firmware to Flash memory or shadow program
memory, and supports a software debugger.
Two CAN controllers support CAN protocol 2.0
parts A & B, data rate is up to 1 Mbit/s. (FT900
and FT902 only)
One SPI master supports single / dual / quad
modes of data transfer. Clock rate is up to 25
MHz
Two SPI slaves support single data transfer
with 25MHz clock.
Two I
