The device has a wide range of features that make it ideal for a variety of applications.

General Overview

The CY8C27243-24SXI is a 16-bit microcontroller that consists of an embedded 8051 core, 256K bytes of Flash memory and 8K RAM. It is pin compatible with other Cypress 8051 products such as the CY8C28x52A/C-24SXI and is supported by a large number of software development tools such as IAR Embedded Workbench and Keil C51 C Compiler. The device is available in an 80-ball Pb-free WLCSP package and comes with an integrated on-chip debugger.

Application Fields

The CY8C27243-24SXI is suitable for a wide range of applications. It can be used to control system level functions such as motor control, audio output, power management, communication, and actuation. It can also be used in general purpose applications such as data acquisition, automotive control, home appliances and consumer electronics. The device is also suitable for industrial automation, gaming, white goods, security systems, and medical devices, among many other applications.

Working Principle

The CY8C27243-24SXI is based on the 8051 core and is capable of operating up to 40 MHz with improved instructions such as parallel processing, 16-bit multiply-accumulate instructions, and multi-word multiplexed instructions. The device is also integrated with essential peripherals such as a capture/compare/PWM module, PSMC module, a 10-bit ADC module, a 3-channel DMA controller, a programmable timer, SPI, I2C and UART, and other peripherals. These peripherals are connected to the CPU core and configured through software. The device is also integrated with on-chip debug support for faster time-to-market.

The device is also integrated with two direct memory access controllers. These controllers are used to transfer data between an external memory and an internal memory, or between two internal memories, while the CPU is running an application program. This feature helps reduce system latency and improves overall performance. In addition, the device also integrates a power management subsystem, which helps reduce system power consumption and improve battery life.
