CA91L862A-50IEV is an interface-specialized, low-voltage, low-power, multi-peripheral, single-chip USB microcontroller. It is designed to simplify the development of applications that have traditionally used larger application-specific processors, while still offering features such as low-power modes, multiple transfers, and a Hi-Speed USB 2.0 interface.

CA91L862A-50IEV is an 8-bit 8051-based core combined with USB 2.0 full-speed peripheral and audio interfaces and contains a 2KB ROM, 32KB RAM and 16KB CPU program memory. The CA91L862A-50IEV also incorporates a real-time clock/calendar, two three-channel CODECs and a configurable digital-to-analog converter.

This device integrates many powerful features and flexible functions to effectively reduce and simplify development cycles. It has a variety of peripheral interface for smart control including SCI, SPI and I2S, providing a wide range of applications including consumer, automotive and industrial. It also has a secure erase and program feature, allowing secure operations with safety, reliability and effectiveness.

The CA91L862A-50IEV integrates a wide range of features and functions, providing highly-specialized user-level variable access and control. The SCI interface is used with a variety of external devices such as LCDs and sensors. The SPI interface can be used with external RAM, EEPROM, ADCs, DACs and other peripheral devices. The I2S interface is used to stream data to other external devices such as codecs, microphones, processors and Amplifiers.

The CA91L862A-50IEV is designed to facilitate real-time in-the-loop control over the system, allowing for a high degree of dynamic control over the system. It can be configured to automatically switch between specific power modes, such as Sleep, Standby, Active and Deep Sleep, for maximum power efficiency.

The CA91L862A-50IEV also offers an integrated Audio Module that supports two 16-bit CODECs which can be used for stereo audio in a variety of audio applications. It also offers a configurable Digital-to-Analog Converter (DAC) to provide a high-resolution output of up to 16 bits. Incorporated in the audio module is a dedicated power management system to minimise power consumption.

The USB 2.0 interface in the CA91L862A-50IEV is able to transfer data at rates between 1.5Mbit/s and 480Mbit/s, making it an effective solution for complicated multi-transfers. It also has low-power modes, including Self-Wakeup, Suspend and Host-Controlled Wakeup, allowing for less magnetic interference and reduced power consumption.

The working principle of the CA91L862A-50IEV is to provide an interface between a host device, such as a computer, and a peripheral device, such as an LCD. The interface consists of a USB 2.0 port and several peripheral interfaces (SCI, SPI, and I²C) which can be used to transfer data. The USB 2.0 port allows for high-speed data transfers while the peripheral interfaces allow for real-time control over the system.

The CA91L862A-50IEV is an ideal device for any application that requires a USB 2.0 interface, audio and peripheral control in a single package. Its integrated Hi-Speed USB 2.0 interface, audio module, power management system and low-power modes make it an effective solution for reducing development time and cost. The CA91L862A-50IEV is an ideal solution for applications such as consumer, automotive, and industrial.
