Infineon Technologies CY7C64215-28PVXIT

Overview

CY7C64215-28PVXIT from Infineon Technologies (formerly Cypress Semiconductor) is a full-speed USB 2.0 microcontroller featuring an M8C Harvard-architecture CPU running up to 24 MHz, 16 KB flash, 1 KB SRAM, and integrated analog/digital blocks for configurable peripheral synthesis. It operates from 3.15 V to 5.25 V, supports industrial temperature range (–40 °C to +85 °C) with external oscillator, and delivers USB-IF certified 12 Mbps communication with no external crystal required for standard operation.

For engineers reviewing the CY7C64215-28PVXIT datasheet, CY7C64215-28PVXIT pinout, CY7C64215-28PVXIT application, or CY7C64215-28PVXIT equivalent, key selection criteria include its on-chip 24/48 MHz IMO with ±0.25% USB-tuned accuracy, six analog blocks supporting up to 14-bit delta-sigma ADCs, four digital blocks enabling UART/I²C/SPI/PWM, and 28-pin SSOP package with 22 GPIOs and programmable drive modes.

Technical Context

The CY7C64215-28PVXIT implements a configurable PSoC-style architecture where four digital enCoRe III blocks and six analog enCoRe III blocks interconnect via global buses to form custom peripherals - including 8-/16-bit PWMs, UARTs, I²C masters, SPI interfaces, and delta-sigma ADCs. Its M8C core executes at up to 24 MHz with interrupt support for 20 vectors and integrates ISSP for in-system programming.

USB functionality is implemented as a dedicated full-speed (12 Mbps) controller with five endpoints (four unidirectional + one bidirectional control), 256-byte dedicated buffer, and internal oscillator self-calibration to ±0.25% for USB compliance. Clocking includes a 24 MHz IMO (doubled to 48 MHz for USB), 32 kHz ILO for sleep/WDT, and optional ECO support - though ECO is not available in the 28-pin SSOP package.

FAQ

Does CY7C64215-28PVXIT support crystal-less USB operation across its full voltage range?

Yes - the device supports crystal-less USB operation at 12 Mbps within two voltage windows: 3.15–3.5 V and 4.35–5.25 V. The internal 24 MHz IMO self-calibrates to ±0.25% accuracy for USB timing compliance in both ranges, eliminating need for external crystal or oscillator in standard configurations.

Can the analog blocks be used simultaneously for ADC and comparator functions?

Yes - the six analog blocks operate independently and can be configured in parallel. For example, three blocks may run delta-sigma ADCs on different input channels while the remaining three implement programmable threshold comparators with hysteresis, all sharing the same analog mux bus without conflict.

What is the maximum number of USB endpoints supported, and how are they allocated?

The CY7C64215-28PVXIT supports five total endpoints: one bidirectional control endpoint (EP0) and four unidirectional endpoints (EP1–EP4). Endpoint direction and transfer type (control/interrupt/bulk) are software-configurable via USB register writes during enumeration, with dedicated 256-byte buffer memory mapped to each active endpoint.

Is the 28-pin SSOP package compatible with the same development tools as the 56-pin QFN variant?

Yes - both packages use identical firmware, PSoC Designer IDE, ISSP programming protocol, and register map. Pin mapping differs, but the underlying architecture, memory layout, clock system, and peripheral configuration logic are fully consistent, enabling seamless migration between packages during design refinement.
