Product details
Overview
CY7C64215-56LFXCT from Cypress Semiconductor is a full-speed USB 2.0 microcontroller (enCoRe™ III architecture) integrating M8C 8-bit Harvard CPU, 16 KB Flash, 1 KB SRAM, 4 digital and 6 analog configurable blocks, and native USB PHY with no external crystal required. It operates at 24 MHz, supports 12 Mbps USB communication, delivers ±0.25% USB clock accuracy via internal oscillator tuning, and targets HID peripheral designs requiring mixed-signal integration and in-system programmability.
For engineers reviewing the CY7C64215-56LFXCT datasheet, CY7C64215-56LFXCT pinout, CY7C64215-56LFXCT application, or CY7C64215-56LFXCT equivalent, key selection criteria include USB endpoint count (5 total), analog resolution (up to 14-bit ΔΣ/Incremental ADC), GPIO drive strength (25 mA sink), programmable clocking (24/48 MHz IMO with USB auto-tuning), and industrial temperature support (–40°C to +85°C with external oscillator).
Technical Context
The CY7C64215-56LFXCT implements a configurable PSoC-style architecture where four digital enCoRe III blocks and six analog blocks interconnect via global buses to form user-defined peripherals - including 8/16-bit PWMs, UART, SPI, I²C master, and ΔΣ/Incremental ADCs. Its M8C core executes at up to 24 MHz with interrupt-driven real-time control and ISSP support.
USB functionality is fully integrated: one bidirectional control endpoint plus four unidirectional endpoints, 256-byte dedicated buffer, and internal oscillator calibrated to ±0.25% for USB compliance without external components - though industrial temperature operation requires an external clock oscillator routed to the 56-pin QFN package's XTAL pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar full-speed USB microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CP2102N-A02-GM | Single-purpose USB-to-UART bridge; no programmable CPU, no analog blocks, no Flash/SRAM | Limited to serial protocol translation; cannot implement custom HID or sensor processing | Select when only UART bridging is needed and firmware customization is unnecessary |
| STM32F072CBT6 | Cortex-M0 core, 128 KB Flash, 16 KB SRAM, USB 2.0 FS, but requires external crystal and lacks integrated analog configurability | Better for complex firmware and higher memory needs; analog subsystem requires external components or dedicated ADCs | Select when ARM ecosystem tooling, larger code space, or deterministic RTOS scheduling is prioritized over analog integration |
Compared with CP2102N-A02-GM and STM32F072CBT6, the CY7C64215-56LFXCT uniquely combines USB 2.0 FS compliance, on-die analog configurability (up to 14-bit ADC), and programmable digital blocks in a single chip - reducing component count for HID and sensor-interface applications where mixed-signal flexibility outweighs raw CPU performance or ARM compatibility.

Manufacturer
Cypress Semiconductor (now part of Infineon Technologies) designs programmable mixed-signal ICs for USB connectivity, human interface, and embedded control applications.
The enCoRe™ III product line was engineered specifically for cost-sensitive, space-constrained USB HID and peripheral devices requiring integrated analog signal conditioning and field-upgradable firmware - not general-purpose microcontrollers.
FAQ
Does CY7C64215-56LFXCT require an external crystal for USB operation?
No - the internal 24 MHz IMO self-tunes to ±0.25% accuracy for USB Full Speed compliance in commercial temperature range (0°C to +70°C). An external crystal is only required for industrial temperature operation (–40°C to +85°C), and only on the 56-pin QFN package where XTALIN/XTALOUT pins are exposed.
How many USB endpoints does CY7C64215-56LFXCT support?
The device supports five total USB endpoints: one bidirectional control endpoint (address 0) and four unidirectional endpoints (addresses 1–4), configurable as IN or OUT. Endpoint buffers are allocated from the dedicated 256-byte USB RAM, with flexible size assignment per endpoint.
Can the analog blocks perform simultaneous dual-channel ADC conversion?
Yes - the Analog Mux Bus is split into two independent sections, allowing concurrent sampling and conversion on two channels. Each analog block can be independently configured as ΔΣ or incremental ADC, and the 8:1 analog input multiplexer on Port 0 provides additional routing flexibility for multi-sensor interfaces.
What development tools are supported for firmware programming?
PSoC Designer™ IDE (Windows XP/Vista) is the official toolset, providing graphical user module configuration, C-code generation, in-circuit emulation, 128 KB trace memory, and ISSP-based programming. Free software, full-featured emulator, and hardware kits (e.g., CY3210-PSoCEval1) are available directly from Infineon/Cypress.
