UMFT200XD-01 Datasheet, PDF (17/28 Pages) List of Unclassifed Manufacturers – FTDI USB Peripheral Series Strategy

FT220X / FT221X Advantages
• Optimal pin / performance choices when IO considerations appear.
− FT220X – 16 pin SSOP/QFN options 1, 2, or 4 bit wide interface.
− FT221X – 20 pin SSOP/QFN options – 1, 2, 4, or 8 bit wide interface.
• Functions similar to SPI slave.
• Low power option – typically 8mA active / 125uA suspend.
• Configurable CBUS pins for BCD, driving LED, clock-out, or GPIO.
• USB Battery Charger Detection function.
• Internal 2KB, MTP could be reprogrammed via USB or FT1248.
• FTDI Chip-ID security feature.
• 1.8V to 3.3V IO (5V Tolerant).
• VCC, 5V (single-supply) or 3.3V.
− Internal regulator for 3.3V supplies.
− Supports Bus-Powered (5V) or Self-Powered (3.3V).
