FAQ
Does CY9AFB44NBBGL-GE1 support USB host and device simultaneously?
Yes. The device integrates a single USB 2.0 physical layer with dual-role capability: it supports Full-Speed device operation (up to 6 endpoints) and Full/Low-Speed host operation (up to 256-byte packets) concurrently. The built-in USB PLL generates required clocks from the main oscillator, and automatic IN/OUT token handling enables reliable enumeration and data transfer in both roles without external PHY.
What is the maximum operating voltage range for CY9AFB44NBBGL-GE1?
The CY9AFB44NBBGL-GE1 operates from 1.65 V to 3.6 V on VCC. When USB functionality is used, VCC must be maintained between 3.0 V and 3.6 V. For LCD operation, the valid range expands to 2.2 V to 3.6 V. These ranges are specified in the Recommended Operating Conditions table (Section 13.2) of Infineon Document 002-05631 Rev. *D.
How many ADC channels does CY9AFB44NBBGL-GE1 support, and what is the conversion speed?
The device integrates two independent 12-bit successive approximation ADC units supporting up to 24 total input channels. Each unit achieves a minimum conversion time of 2.0 μs at supply voltages from 2.7 V to 3.6 V. Conversion can be triggered by software or peripherals, with priority and scanning modes supported, and FIFO buffering for up to 16 results in scan mode.
Is external bus interface supported on CY9AFB44NBBGL-GE1?
No. According to the datasheet (Document 002-05631 Rev. *D, page 2), CY9AFB44NBBGL-GE1 - along with CY9AFB41LB and CY9AFB42LB - does not support the External Bus Interface. This omission reduces pin count and simplifies design for applications that rely solely on on-chip memory and serial peripherals such as USB, UART, and I²C.
