Product details
Overview
CY7C68033-56BAXC from Cypress Semiconductor is a USB 2.0 NAND Flash controller IC integrating an enhanced 8051 core, USB 2.0 transceiver, Smart Serial Interface Engine (SIE), and General Programmable Interface (GPIF) in a single 56-pin QFN package. It supports high-speed (480 Mbps) and full-speed (12 Mbps) USB operation, delivers up to 96 MB/s burst data rate, and implements industry-standard ECC (1-bit correction / 2-bit detection per 256 bytes) for 8-bit NAND Flash with page sizes of 512/2K/4K bytes. It is used in embedded NAND-based mass storage devices such as GPS units, DVB video capture systems, and MP3 players.
For engineers reviewing the CY7C68033-56BAXC datasheet, CY7C68033-56BAXC pinout, CY7C68033-56BAXC application, or CY7C68033-56BAXC equivalent, key selection criteria include its integrated 15 KB on-chip RAM (8 KB default NAND firmware + 7 KB free space), programmable 4× bulk/interrupt/isochronous endpoints with double/triple/quad buffering, 12 GPIOs (including dual dedicated CE# pins), and support for up to eight single-die or four dual-die NAND Flash chips.
Technical Context
The CY7C68033 operates with a 24-MHz external crystal and internal PLL to generate clocks for both USB PHY (480 MHz) and 8051 core (12/24/48 MHz selectable). Its Smart SIE offloads USB protocol handling, enabling the 8051 to focus on NAND management and host command translation.
GPIF provides glueless parallel interface capability via programmable waveform descriptors-supporting 8- or 16-bit bus widths, multiple RDY/CTL signals, and master/slave FIFO modes. The integrated I²C controller (100/400 kHz, master-only) enables communication with external configuration EEPROMs or sensors after NAND initialization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed | High-speed (480 Mbps) and full-speed (12 Mbps); no low-speed support-enables direct connection to PC hosts without hub translation. |
| Core Processor | Enhanced 8051 running at 12/24/48 MHz; executes firmware from internal RAM loaded at boot from NAND-eliminates need for external EEPROM. |
| On-chip RAM | 15 KB total: 8 KB pre-allocated for default NAND firmware, 7 KB available for custom code/data-supports complex wear leveling and bad-block management. |
| NAND Interface | 8-bit parallel interface with configurable timing (30/50/100 ns), SmartMedia-compatible ECC, and up to eight CE# outputs-enables multi-chip NAND arrays up to 16 Gb capacity. |
| Endpoints | Four programmable bulk/interrupt/isochronous endpoints + one additional 64-byte bulk/interrupt endpoint-provides flexible USB transfer architecture for mass storage class compliance. |
| Power Consumption | 43 mA typical active current; 300 µA typical suspend current (CY7C68033-specific)-optimized for non-battery-powered USB peripherals requiring stable thermal profile. |
| I/O Capability | 12 fully programmable GPIOs, including two dedicated CE# pins and six configurable CE#/GPIO pins-allows dynamic reassignment for system-level pin multiplexing. |
Pinout & Package
Package: 56-pin QFN (7 mm × 7 mm, 0.5 mm pitch), thermally enhanced with exposed pad. RoHS-compliant, lead-free, and moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D+ / D− | USB 2.0 differential data pair | Integrated transceiver eliminates external PHY; requires 27 Ω series resistors and 1.5 kΩ pull-up on D+ for high-speed enumeration. |
| XTALIN / XTALOUT | 24 MHz crystal oscillator inputs | Drives on-chip PLL; requires 12 pF load capacitors and ±100 ppm stability for USB timing compliance. |
| CE[0:7] | NAND chip enable outputs | Eight dedicated CE# signals-supports up to eight single-die or four dual-die NAND devices; CE[0] and CE[1] are hardwired, others configurable. |
| RDY[0:1] | NAND ready status inputs | Two asynchronous RDY inputs allow handshake synchronization with NAND latency variations across vendors and densities. |
| CTL[0:2] | General-purpose control outputs | Three programmable CTL outputs used for NAND write protect, reset, or auxiliary peripheral signaling-configurable via GPIF descriptor. |
| IOA–IOD | Programmable I/O ports | Four 8-bit bidirectional ports (32 pins total); multiplexed for GPIF data/address bus, I²C, or GPIO-default firmware uses IOB/IOD for 8-bit NAND data/address bus. |
Key Features
| Feature | Design Value |
|---|---|
| Smart SIE with vectored USB interrupts | Reduces 8051 firmware overhead by >70% for standard USB control transfers and endpoint management-accelerates development of Mass Storage Class-compliant devices. |
| Programmable GPIF with waveform descriptors | Enables zero-glue interface to ASICs, DSPs, or legacy buses (EPP, UTOPIA, PCMCIA) without FPGA or CPLD-reduces BOM cost and PCB layer count. |
| Integrated I²C master controller | Supports 100/400 kHz operation with open-drain SCL/SDA-allows runtime configuration of external power monitors or sensor registers after NAND initialization. |
| On-chip ECC engine (1-bit correct / 2-bit detect) | Hardware-accelerated error correction per 256-byte sector-eliminates software ECC overhead and ensures NAND reliability over 100K program/erase cycles. |
| Flexible suspend/resume behavior | 300 µA typical suspend current with fast wake-on-USB-event-meets USB 2.0 remote wakeup requirements while minimizing standby power in desktop-attached peripherals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB NAND Flash controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C68034-56BAXC | Same silicon, lower suspend current (100 µA vs. 300 µA); identical pinout and firmware compatibility. | Targeted for battery-powered devices (e.g., handheld scanners); not rated for continuous 43 mA active draw in mains-powered designs. | Select CY7C68034 only when <300 µA suspend current is mandatory and thermal budget allows same active power. |
| SL11H-2000-BZ | Legacy USB 1.1-only controller; no integrated 8051 or GPIF; requires external microcontroller and NAND controller logic. | Limited to 12 Mbps transfers; lacks hardware ECC and multi-chip CE# support-suitable only for low-capacity, low-cost legacy designs. | Choose only for cost-sensitive, low-bandwidth applications where USB 2.0 speed and NAND scalability are unnecessary. |
Compared with CY7C68034-56BAXC, the CY7C68033-56BAXC offers higher suspend current tolerance for fixed-power systems, while SL11H-2000-BZ lacks integrated processing and NAND management-making CY7C68033 the only option supporting high-speed, firmware-flexible, multi-NAND-chip USB mass storage with hardware ECC.

FAQ
Does CY7C68033-56BAXC require external RAM or EEPROM for operation?
No. The device includes 15 KB of on-chip RAM, with 8 KB pre-allocated for default NAND firmware and 7 KB available for custom code. Firmware is loaded from NAND Flash at startup, eliminating the need for external non-volatile memory. Internal ROM provides fallback manufacturing-mode descriptors when NAND is absent or invalid.
What NAND Flash page sizes and densities does CY7C68033-56BAXC support?
It supports 512-byte pages (up to 1 Gb), 2 KB pages (up to 8 Gb), and 4 KB pages (up to 16 Gb) per chip select. Up to eight single-die or four dual-die NAND devices can be connected using its eight CE# outputs, with configurable timing for 30/50/100 ns NAND parts.
Can the GPIF interface be used for non-NAND protocols like EPP or UTOPIA?
Yes. The General Programmable Interface (GPIF) supports fully customizable waveform descriptors and up to three RDY inputs and three CTL outputs. Reference designs confirm working implementations with EPP printers and UTOPIA Level 2 ATM interfaces-no external logic required.
Is CY7C68033-56BAXC compatible with USB 3.0 hosts?
It operates exclusively in USB 2.0 mode (high-speed or full-speed) and connects to USB 3.0 hosts via backward-compatible USB 2.0 lanes. No USB 3.0 SuperSpeed functionality is supported, but enumeration and data transfer behave identically to any certified USB 2.0 device on USB 3.0 ports.
