This device is intended for embedded systems applications, including those found in the consumer, automotive and industrial fields. The CY7C64316-16LKXC features multiple interfaces, such as general purpose digital I/O, serial communications, Timers, PWM, analog and digital Comparators, and Data FIFO, amongst other features.

Architecture and Features

The CY7C64316-16LKXC architecture consists of a Microarchitecture which consists of a 16-bit Reduced Instruction Set Computer (RISC) processor core with 16 kB of on-chip SRAM, 16 kB of on-chip program memory, 8-channel 8-bit Analog-to-Digital Converter (ADC), four 8-bit Digital-to-Analog Converters (DAC) and four 8-bit Programmable Pulse Width Modulators (PWM). The device also has a collection of highly efficient peripherals and provides code-compatible support for various interfaces such as Universal Serial Bus (USB 2.0), I2C, SPI, UART and the CoreConnect bus. In addition, on-chip memory and peripherals are capable of executing arithmetic functions, such as Floating-Point multiplications, found in popular digital signal processing (DSP) applications.

The Operating Modes

The CY7C64316-16LKXC device is capable of operating in two modes. The GPIO mode is used for low power digital I/O operations, while the CoreConnect mode is used for data transfer and digital signal processing operations.

GPIO Mode

In GPIO mode, the CY7C64316-16LKXC provides 8 channelled 8-bit general purpose I/Os (GPIOs) and operates in active, low power, suspension or sleep modes. GPIOs can handle inputs and outputs of up to 4.5V. The rate of the GPIOs has a maximum of 2 MHz, and they have internal Pull Up or Pull Down resistors to drive the output.

Core Connect Mode

In CoreConnect mode, the CY7C64316-16LKXC can be programmed to run digital signal processing operations. It is compliant with the CoreConnect peripheral bus, which enables serial communication, interrupt handling, and DMA functionality. The CoreConnect bus supports communication speeds up to 12.41 Mbps, with a 3.3V logic level. The CoreConnect interface also supports the use of upstream and downstream keying functions, allowing the CY7C64316-16LKXC to be used for communication with multiple other devices.

The Power Supply Environment

The CY7C64316-16LKXC is capable of operating with a variety of power supplies and input voltages between 3.3 and 5.5V. It can also handle varying output and current demands depending on system requirements, making it suitable for a range of embedded applications.
