Description

Product Overview

The CY8C27443-24SXI is a PSoC 1 (Programmable System-on-Chip) from Infineon Technologies (formerly Cypress Semiconductor) featuring an M8C 8-bit core at 24MHz, 16KB Flash, 256 bytes SRAM, and a unique array of configurable digital and analog blocks. It provides 8 digital PSoC modules and 12 analog PSoC modules in a 28-pin SOIC package, enabling highly integrated mixed-signal designs.

  • Motor control and drive systems
  • Home appliance controllers
  • Portable instrumentation

The CY8C27443-24SXI is a Programmable System-on-Chip (PSoC) from Infineon Technologies that redefines the traditional MCU paradigm by providing configurable analog and digital blocks alongside the M8C 8-bit processor core. With 8 digital PSoC modules and 12 analog PSoC modules, designers can create custom peripherals by routing and interconnecting these blocks using PSoC Designer IDE. The 14-bit ADC, 9-bit DAC, programmable gain amplifiers, and filters can all be configured without external components, significantly reducing BOM count and board space. The SXI suffix denotes SOIC-28 package with industrial temperature range.

The CY8C27443-24SXI operates on the PSoC architecture where the M8C 8-bit CPU core executes user code from Flash memory while the configurable digital and analog blocks operate semi-autonomously. The 8 digital blocks can each be configured as one of several digital peripherals (8/16/24/32-bit timers, counters, UART, SPI, CRC, or pseudo-random sequence generators). The 12 analog blocks are organized in 4 columns of 3 blocks each, and can be configured as continuous-time blocks (PGAs, comparators) or switched-capacitor blocks (ADCs, DACs, programmable filters). Interconnections between blocks and I/O pins are made through a programmable routing network, enabling signal chains that would otherwise require multiple discrete ICs. The CPU interacts with the configured blocks through registers and interrupts.

Pin Name Function
1 P1[0] Port 1, Bit 0 (Digital/Analog I/O)
2 P1[1] Port 1, Bit 1 (Digital/Analog I/O)
3 P1[2] Port 1, Bit 2 (Digital/Analog I/O)
4 P1[3] Port 1, Bit 3 (Digital/Analog I/O)
5 P1[4] Port 1, Bit 4 (Digital/Analog I/O)
6 P1[5] Port 1, Bit 5 (Digital/Analog I/O)
7 P1[6] Port 1, Bit 6 (Digital/Analog I/O)
8 P1[7] Port 1, Bit 7 (Digital/Analog I/O)
9 VSS Ground
10 VDD Power Supply (3.0V ~ 5.25V)

The CY8C27443-24SXI excels in applications requiring custom mixed-signal functionality that would traditionally need multiple ICs. In industrial sensor interfaces, the configurable analog blocks can implement signal conditioning chains (PGA → filter → ADC) without external op-amps. For motor control, the digital blocks can generate PWM signals while the analog blocks handle current sensing and overcurrent protection. The PSoC approach is particularly valuable in home appliances where a single device can replace an MCU plus several analog ICs, reducing cost and board space. The ISSP capability enables firmware updates in the field.
