Infineon Technologies CY7C60323-PVXC

Overview

CY7C60323-PVXC from Cypress Semiconductor is an 8-bit Harvard-architecture M8C microcontroller operating from 2.4 V to 3.6 V (or down to 1.0 V with on-chip switch mode pump), featuring 8 KB flash, 512 bytes SRAM, 10-bit and 8-bit ADCs, full-duplex SPI, I²C up to 400 kHz, and 24 GPIOs in a 28-pin SSOP package - used in wireless human interface devices including gamepads and presenter tools.

For engineers reviewing the CY7C60323-PVXC datasheet, CY7C60323-PVXC pinout, CY7C60323-PVXC application, or CY7C60323-PVXC equivalent, key selection criteria include low-voltage operation (1.0–3.6 V), integrated SMP for single-cell battery support, configurable analog/digital blocks, ISSP capability, and GPIO drive strength (10 mA) with programmable pull-up/pull-down modes.

Technical Context

The CY7C60323-PVXC implements a fixed-function PSoC 1 architecture with four digital and four analog user-module-capable blocks, supporting dynamic reconfiguration of peripherals via PSoC Designer. Its M8C core runs at up to 12 MHz (4 MIPS) and integrates IMO (24/48 MHz ±2.5%) and ILO oscillators for clocking flexibility.

System-level resources include a 1.3 V internal voltage reference, programmable low-voltage detection, power-on reset, watchdog timer, sleep timer, and a switch mode pump enabling operation from 1.2 V battery cells. All 24 GPIOs support interrupt configuration, analog input multiplexing, and multiple drive modes (strong, open-drain, high-Z, pull-up/down).

FAQ

Does CY7C60323-PVXC support USB natively?

No. The CY7C60323-PVXC does not include a USB physical layer or USB controller. It is designed for HID applications that interface to USB hosts via external USB-to-serial bridges (e.g., CP2102) or proprietary 2.4 GHz RF dongles. Its I²C and SPI interfaces enable communication with such companion chips.

What is the role of the switch mode pump (SMP) in this device?

The SMP generates a regulated ~3.3 V supply from a single 1.2 V battery cell, enabling full functionality (including flash programming and ADC operation) at voltages as low as 1.0 V. It eliminates the need for external boost converters in compact, single-cell consumer devices like wireless remotes and gamepads.

Can the 10-bit and 8-bit ADCs operate simultaneously?

No. The CY7C60323-PVXC contains one 10-bit SAR ADC and one 8-bit successive approximation ADC sharing the same analog mux bus and reference. They cannot sample concurrently; time-multiplexed operation is required, with typical conversion times of 20 µs (10-bit) and 5 µs (8-bit) at maximum clock rates.

Is PSoC Designer software still supported for CY7C60323-PVXC development?

Yes. Cypress provides legacy support for PSoC Designer v5.4, including full device libraries, debug drivers, and ISSP programming utilities for CY7C603xx devices. While no new features are added, the toolchain remains functional on Windows 7/10 and is distributed via Infineon's archived design resources portal.
