5 / 29 page  CY7C65213 CY7C65213A Document Number: 001-81011 Rev. *M Page 5 of 29 application reduces device data backlog. After it reaches the 75% watermark level, the RTS# signal is asserted to resume data reception. ■ DSR# (Input) / DTR# (Output) The DSR#/DTR# signals are used to establish a communication link with the UART. These signals complement each other in their functionality, similar to CTS# and RTS#. GPIO Interface CY7C65213/CY7C65213A has eight GPIOs. The configuration utility lets you configure the GPIO pins. The configurable options are as follows: ■ TRISTATE: GPIO tristated ■ DRIVE 1: Output static 1 ■ DRIVE 0: Output static 0 ■ POWER#: Power control for bus power designs ■ TXLED#: Drives LED during USB transmit ■ RXLED#: Drives LED during USB receive ■ TX or RX LED#: Drives LED during USB transmit or receive. GPIO can be configured to drive LED at 8-mA drive strength. ■ SLEEP#: Indicates USB suspend ■ BCD0/1: Two-pin output to indicate the type of USB charger ■ BUSDETECT: Connects VBUS pin for USB host detection Memory CY7C65213/CY7C65213A has a 512-byte flash. Flash is used to store USB parameters, such as VID/PID, serial number, and Product and Manufacturer Descriptors, which can be programmed by the configuration utility. System Resources Power System CY7C65213/CY7C65213A supports the USB Suspend mode to control power usage. CY7C65213/CY7C65213A operates in bus-powered or self-powered modes over a range of 3.15 V to 5.5 V. Clock System CY7C65213/CY7C65213A has a fully integrated clock and does not require any external crystal. The clock system is responsible for providing clocks to all subsystems. Internal 48-MHz Oscillator The internal 48-MHz oscillator is the primary source of internal clocking in the CY7C65213/CY7C65213A device. Internal 32-kHz Oscillator The internal 32-kHz oscillator is the primary source of internal clocking in CY7C65213/CY7C65213A. Reset The reset block ensures reliable power-on reset and brings the device back to the default known state. The RESET# (active low) pin can be used by external devices to reset the CY7C65213/CY7C65213A. Suspend and Resume The CY7C65213/CY7C65213A device asserts the SLEEP# pin when the USB bus goes into the suspend state. This helps to meet the stringent suspend current requirements of the USB 2.0 specification, while using the device in bus-powered mode. The device resumes from the suspend state under either of the following two conditions: 1. Any activity is detected on the USB bus 2. The RI# (configured as wakeup) pin is asserted to generate remote wakeup to the host. WAKEUP The RI# (configured as wakeup) pin is used to generate the remote wakeup signal on the USB bus. The remote wakeup signal is sent only if the host enables this feature through the SET_FEATURE request. The device communicates support for the remote wakeup to the host through the configuration descriptor during the USB enumeration process. The CY7C65213 device allows enabling/disabling of the remote wakeup feature through the configuration utility. Software Cypress delivers a complete set of software drivers and a configuration utility to enable product configuration during system development. Drivers for Linux Operating Systems Cypress provides a User Mode USB driver library (libcyusbserial.so) that abstracts vendor commands for the UART interface and provides a simplified API interface for user applications. This library uses the standard open-source libUSB library to enable USB communication. The Cypress serial library supports the USB plug-and-play feature using the Linux ‘udev’ mechanism. CY7C65213/CY7C65213A supports the standard USB CDC UART-class driver, which is bundled with the Linux kernel. Android Support The CY7C65213/CY7C65213A solution also includes an Android Java class–CyUsbSerial.java–which exposes a set of interface functions to communicate with the device. Drivers for Mac OSx Cypress delivers a dynamically linked shared library (CyUSBSerial.dylib) based on libUSB, which enables communication to the CY7C65213/CY7C65213A device. In addition, the device also supports the native Mac OSx CDC UART-class driver. |
