CY8C3246LTI-162T

Updated: 2026-07-24

Overview

The CY8C3246LTI-162T is a member of Infineon's PSoC 3 family, featuring a 32-bit ARM Cortex-M3 core with programmable analog and digital peripherals. It is designed for applications requiring high flexibility and integration, such as industrial control systems, consumer electronics, and IoT devices. The device stands out for its mixed-signal capabilities, allowing designers to configure custom analog front-ends and digital logic without external components. This reduces BOM costs and board space while accelerating development cycles.

Structure and Working Principle

The CY8C3246LTI-162T integrates a 32-bit MCU core with up to 16KB SRAM and 64KB flash memory. Its unique feature is the programmable analog and digital blocks, which can be configured as ADCs, DACs, op-amps, timers, or UARTs through PSoC Creator software. The chip operates on a 1.71V to 5.5V supply range, supporting low-power modes for battery-operated applications. The digital system includes DMA controllers and programmable logic blocks, while the analog subsystem offers precision analog components with 20-bit resolution in some configurations.

Key Features

Key features include a 67MHz Cortex-M3 core, 16KB SRAM, 64KB flash, and up to 36 programmable GPIOs. The analog subsystem includes 12-bit ADCs, 8-bit DACs, and programmable gain amplifiers. The device supports CapSense technology for touch sensing applications, eliminating mechanical buttons. It also features low-power modes (down to 1µA in sleep mode) and extensive communication interfaces including I2C, SPI, and UART.

Application Areas

Common applications include industrial control systems, medical devices, consumer appliances, and IoT edge nodes. Its programmable nature makes it suitable for motor control, power management, and human-machine interfaces. In consumer electronics, it's used in smart home devices, wearables, and touch panels. Industrial applications include sensor conditioning, process control, and automation systems where custom signal processing is required.

Maintenance and Precautions

When handling the CY8C3246LTI-162T, observe standard ESD precautions for semiconductor devices. The chip should be stored in anti-static packaging at room temperature with controlled humidity. For programming and debugging, use the recommended MiniProg3 programmer and follow the voltage specifications in the datasheet. Avoid exceeding maximum ratings for supply voltage and I/O currents to prevent damage to the device.

B2B Procurement Guide

For volume purchases, consider authorized distributors like Digi-Key, Mouser, or Arrow Electronics. Lead times typically range from 4-8 weeks for standard quantities. Evaluate alternative PSoC 3 or PSoC 5LP devices if specific features aren't required. Request samples and development kits to test functionality before committing to large orders. Consider long-term availability as Infineon periodically updates its product lifecycle status.
