FT930/1/2/3
(
Embedded Microcontroller)
The FT93x series includes the FT930, FT931, FT932
and FT933 which are complete System-On-Chip 32-bit
RISC microcontrollers for USB to multi-interface
bridging and embedded applications featuring a high
level of integration and low power consumption. With a
D2XX
1
hardware engine built-in, it is compatible with
D2XX drivers. It has the following features:
High performance, low power mixed 16-bit/32-bit
FT32B core processor, running at a frequency of
100MHz.
128kB on-chip Flash memory.
128kB on-chip shadow program memory.
True Zero Wait States (0WS) up to 3.1 DMIPS per
MHz performance.
32kB on-chip data memory.
Integrated Phase-Locked Loop (PLL) supports
single external 12MHz crystal and direct external
clock source input.
Real Time Clock (RTC) with automatic calibration
to compensate for inaccuracies in low-cost 32.768
kHz crystal or other input source.
D2XX hardware engine (USB 2.0 Device) with up
to 7 interfaces
One USB 2.0 Device controller supports high-speed
(480 Mbit/s) and full-speed (12 Mbit/s).
USB2.0 Device controller supports Isochronous,
Interrupt, Control, and Bulk transfers for up to 15
endpoints
Supports One-Wire for firmware download and
software debugging.
One SPI Master supports single/dual/quad modes
of data transfer. Clock rate is up to 25 MHz
One SPI Slave supports single data transfer up to
25MHz.
SD Host Controller conformant to SDA SD Host
Controller specification V3.0, running up to 25
MHz and software support for SD/SDHC/SDXC
cards
I2C bus interfaces may be configured as master
or slave, supporting standard/fast /fast plus/high
speed mode data transfers. Max data transfer rate
up to 3.4 Mbit/s. Clock stretching is supported.
Four UARTs configurable as two
interfaces or 4 half UART interfaces
full
UART
Four 16-bit timers with prescaler and one 32-bit
watchdog timer.
Supports eight independent PWM channels. PWM
Channel 0 and 1 may be configured as stereo
audio output channels, supporting PCM 8-bit/16-
bit stereo data.
Supports two independent 10-bit DACs. DAC 0/1
channel output. Sample rate of ~1MS/s.
Supports three 8-bit ADC1/2/3 channel input.
Sample rate of ~480KS/s.
Single 3.3 volt power supply, built-in 1.2 V
regulator.
3.3 volt I/O power supply, all GPIO pins are 5V
tolerant.
Supports USB Battery Charging Specification Rev
1.2.
Power-On Reset (POR).
-40°C to 85°C extended operating temperature
range.
Available in compact Pb-free, RoHS compliant 68
to 48-pin packages.
