FT221X USB 8-BIT SPI/FT1248 IC Datasheet

Version 1.3

Document No.: FT_000630 Clearance No.: FTDI# 263

Future Technology Devices

International Ltd

FT221X

(USB 8-Bit SPI/FT1248 IC)



USB Battery Charger Detection. Allows for USB

peripheral devices to detect the presence of a

higher power source to enable improved

charging.

The FT221X is a USB to FTDI’s

proprietary FT1248 interface with the

following advanced features:



Single chip USB to 1, 2, 4, or 8 bit wide

synchronous interface.



Device supplied pre-programmed with unique

USB serial number.



Similar to an SPI Slave with variable bus width.

USB Power Configurations; supports bus-

powered, self-powered and bus-powered with

power switching.

Entire USB protocol handled on the chip. No

USB specific firmware programming required.



Integrated +3.3V level converter for USB I/O.



Fully

integrated

2048

byte

multi-time-

programmable (MTP) memory, storing device

descriptors and CBUS I/O configuration.

True 3.3V CMOS drive output and TTL input;

operates down to 1V8 with external pull-ups.

Tolerant of 5V inputs.

Fully integrated clock generation with no

external crystal required plus optional clock

output selection enabling a glue-less interface

to external MCU or FPGA.



Configurable I/O pin output drive strength; 4

mA(min) and 16 mA(max)



Integrated power-on-reset circuit.



Data transfer rates to 1MByte/s.

Fully integrated AVCC supply filtering - no

external filtering required.

512 byte receive buffer and 512 byte transmit

buffer utilising buffer smoothing technology to

allow for high data throughput.



+ 5V Single Supply Operation.

Internal 3V3/1V8 LDO regulators



FTDI’s royalty-free Virtual Com Port (VCP) and

Direct

requirement for USB driver development in

most cases.

(D2XX)

drivers

eliminate

the

Low operating and USB suspend current; 8mA

(active-typ) and 125uA (suspend-typ).



Low USB bandwidth consumption.

UHCI/OHCI/EHCI host controller compatible.

USB 2.0 Full Speed capable.

Configurable CBUS I/O pin.

Extended operating temperature range; -40 to

85⁰C.



Available in compact Pb-free 20 Pin SSOP and

QFN packages (both RoHS compliant).
