CY8C21312-24PVXA

Product Overview

The CY8C21312-24PVXA from Cypress Semiconductor Corp is an 8-bit microcontroller built around the M8C core and operating at 24 MHz. It provides 8KB (8K x 8) of FLASH program memory, 512 x 8 bytes of RAM, and 16 I/O lines in a 20-SSOP surface-mount package. The device supports I2C, SPI, and UART/USART communication, includes LVD, POR, PWM, and WDT peripherals, and uses an internal oscillator. It is specified for a 3 V to 5.25 V supply and an operating temperature range of -40°C to 85°C.

Key Features

• M8C 8-bit core with 24 MHz operating speed and internal oscillator.
• 8KB (8K x 8) FLASH program memory and 512 x 8 bytes of RAM.
• 16 I/O lines and 20-SSOP (0.209 inch, 5.30 mm width) surface-mount package.
• I2C, SPI, and UART/USART connectivity for serial communication with external devices.
• LVD, POR, PWM, and WDT peripherals support voltage monitoring, power-on reset, pulse-width modulation, and watchdog timing.
• 3 V to 5.25 V supply range and -40°C to 85°C operating temperature range.

Applications

• Embedded control modules that need I2C, SPI, or UART/USART communication with sensors, displays, or host processors.
• Compact 3 V to 5.25 V digital control nodes using 16 I/O lines and surface-mount assembly.
• Control and monitoring functions that use PWM outputs, watchdog timing, power-on reset, and low-voltage detection.
• Board-level designs operating from -40°C to 85°C with FLASH program memory and an internal oscillator.

Design & Procurement Notes

Designers should confirm that the 20-SSOP footprint, 16 I/O count, 3 V to 5.25 V supply, and -40°C to 85°C temperature range match the board and environment. The 8KB FLASH and 512 x 8 bytes of RAM set the program and data limits, while the M8C core, 24 MHz speed, and internal oscillator define the execution and timing framework. I2C, SPI, UART/USART, LVD, POR, PWM, and WDT should be mapped against required communication, supervision, and output-control needs before finalizing the design.
