No Preview Available ! ISP1110 Universal Serial Bus transceiver with UART signaling Rev. 02 — 19 March 2007 Product data sheet 1. General description The ISP1110 is a Universal Serial Bus (USB) transceiver that supports Universal Asynchronous Receiver-Transmitter (UART) signaling mode. The ISP1110 USB transceiver is fully compliant with Universal Serial Bus Speciﬁcation Rev. 2.0. The ISP1110 can transmit and receive USB data at full-speed (12 Mbit/s). The ISP1110 transceiver allows USB Application Speciﬁc Integrated Circuits (ASICs) with I/O power supply voltage from 1.65 V to 2.85 V to interface to the physical layer of the USB. The transceiver has an integrated 5 V-to-3.3 V voltage regulator for direct powering through USB supply line VBUS and an integrated voltage detector to detect the presence of the VBUS voltage on the VCC(5V0) pin. When VBUS is present, the transceiver is in USB mode. When VBUS is not present, the transceiver can be set to UART signaling mode. The ISP1110 transceiver is available in HBCC16 lead-free and halogen-free package. 2. Features I Fully complies with Universal Serial Bus Speciﬁcation Rev. 2.0 I Supports USB data transfer at full-speed (12 Mbit/s) I Integrated DP pull-up resistor to reduce external components I Implemented internal DP pull-up resistor as described in ECN_27%_Resistor I Integrated 5 V-to-3.3 V voltage regulator to power through USB line VBUS I VBUS voltage presence is indicated on pin VBUSDET I Pins VP and VM function in bidirectional mode, allowing pin count saving for ASIC interface I Used as a USB peripheral transceiver I Stable RCV output during Single-Ended Zero (SE0) condition I Two single-ended receivers with hysteresis I Low-power operation I Supports 2.8 V UART signaling mode on the DP and DM lines I Supports VCC(I/O) voltage range from 1.65 V to 2.85 V I Supports VCC(UART) voltage range from 2.7 V to 4.5 V I Off-state supply current from VCC(UART) is less than 3 µA I Static current from VCC(I/O) is less than 3 µA (typical 1 µA) I Available in small HBCC16 (3 mm × 3 mm) lead-free and halogen-free package 1 page NXP Semiconductors ISP1110 USB transceiver with UART signaling Table 2. Pin description …continued Symbol[1] Pin Type[2] Description VCC(5V0) 12 - supply voltage input (4.0 V to 5.5 V); can be directly connected to USB line VBUS VCC(UART) 13 - supply voltage input (2.7 V to 4.5 V) for the UART signaling VREG 14 - internal regulator output; a decoupling capacitor of at least 0.1 µF is required VCC(I/O) 15 - supply voltage for digital I/O pins (1.65 V to 2.85 V). When VCC(I/O) is not connected, the DP and DM pins are in off-state. This supply pin is totally independent of VCC(5V0) and VREG, and must never exceed VREG. UART_EN 16 I enable UART signaling mode when VCC(5V0) is not present input pad; push-pull; CMOS GND exposed - die pad ground supply; down bonded to the exposed die pad (heat sink); to be connected to the PCB ground [1] Symbol names ending with underscore N, for example, _N, indicate active LOW signals. [2] I = input; O = output; I/O = digital input/output; AI/O = analog input/output. ISP1110_2 Product data sheet Rev. 02 — 19 March 2007 © NXP B.V. 2007.
