FT905/6/7/8
(
Embedded Microcontroller)
The FT90x series includes the FT905,
FT906, FT907 and FT908 which are
complete System-On-Chip 32-bit RISC
microcontrollers
for
embedded
applications featuring a high level of
integration
and
low
power
consumption. They have the following
features:
High performance, low power 32-bit FT32core
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 (480Mbit/s), full-speed
(12Mbit/s), and low-speed (1.5Mbit/s).
One USB2.0 peripheral controller supports
high-speed
(480Mbit/s)
and
full-speed
(12Mbit/s).
USB2.0 host and peripheral controllers support
the Isochronous, Interrupt, Control, and Bulk
transfers.
Supports USB Battery Charging Specification
Rev 1.2. Downstream port can be configured as
SDP, CDP or DCP. Upstream port can perform
BCD mode detection.
10/100Mbps Ethernet that is compliant with the
IEEE 802.3/802.3u standards. (FT905 and
FT906 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 protocol2.0
parts A&B, data rate is up to 1Mbit/s. (FT905
and FT907 only).
