Product details

Overview

CY7C63001C-PXC from Cypress Semiconductor is an 8-bit RISC OTP microcontroller with integrated low-speed USB 1.1 transceiver, optimized for human-interface devices. It features 4 KB EPROM, 128-byte RAM, 12 GPIOs (8 low-current P0 + 4 high-current P1), 6-MHz ceramic resonator input, and supports one device address with two endpoints (control + data). Used in USB mouse designs requiring Schmitt-trigger I/O, LED drive, and suspend/wake-up via CEXT.

For engineers reviewing the CY7C63001C-PXC datasheet, CY7C63001C-PXC pinout, CY7C63001C-PXC application, or CY7C63001C-PXC equivalent, key selection criteria include USB 1.5 Mbps compliance, 12-GPIO allocation across two ports, programmable sink current per pin, Instant-On Now™ suspend/wake timing, and PDIP-20 package compatibility with industry-standard programmers.

Technical Context

The CY7C63001C implements a Harvard-architecture RISC core running at 12 MHz (doubled from 6-MHz external ceramic resonator), executing 35 USB-optimized instructions. Its USB Serial Interface Engine (SIE) handles low-speed (1.5 Mbps) protocol framing, endpoint management, and CRC generation without CPU intervention.

Memory includes 4 KB of OTP EPROM (with 16-byte interrupt vector table) and 128-byte RAM-16 bytes reserved for dual 8-byte USB FIFOs (Endpoint 0 and 1). The device supports three reset sources (POR, WDR, USB Bus Reset), each flagged in Status and Control Register (0xFF), and uses separate Program Stack Pointer (PSP) and Data Stack Pointer (DSP) with user-configurable initialization.

Key Specifications

Parameter	Value and Actual Design Meaning
USB Speed	1.5 Mbps low-speed compliant with USB 1.1 - enables cost-effective HID peripheral design without external PHY.
Microcontroller Core	8-bit RISC Harvard architecture @ 12 MHz - delivers deterministic timing for real-time USB packet handling.
Memory	4 KB EPROM + 128-byte RAM - sufficient for HID descriptor parsing, report processing, and state machine logic.
I/O Pins	12 total GPIOs: P0.0–P0.7 (low-current, Schmitt-trigger) + P1.0–P1.3 (high-current, LED-drive capable) - supports direct LED/analog sensor interfacing.
Power Supply	4.0 V to 5.25 V - compatible with standard USB VBUS and legacy 5 V rail systems without LDO.
Suspend/Wake	Instant-On Now™ mode with <256 µs wake latency - enables periodic polling of optical encoders or potentiometers while maintaining sub-100 µA average current.
Package	20-pin PDIP (PXC suffix) - through-hole mount for prototyping and legacy PCB assembly.

Pinout & Package

Package: 20-pin Plastic Dual In-line Package (PDIP), 0.3-inch body width, lead pitch 0.1 inch.

Pin/Terminal	Circuit Role	Design Meaning
P0.0–P0.7	Low-current GPIO port with Schmitt trigger input	Configurable as interrupt sources or digital inputs; internal pull-up programmable; sink current adjustable in 16 levels.
P1.0–P1.3	High-current GPIO port with LED drive capability	Capable of sourcing/sinking up to 20 mA per pin - directly drives status LEDs without external drivers.
D+, D–	USB differential data lines	Bidirectional low-speed USB interface; requires external 1.5 kΩ pull-up on D– to VCC for device enumeration.
XTALIN/XTALOUT	6-MHz ceramic resonator interface	Drives internal clock doubler; no external oscillator required - reduces BOM count and layout complexity.
CEXT	Open-drain wake-up timer input/output	Connects to RC network for programmable suspend wake interval; triggers edge-sensitive interrupt upon capacitor discharge.
VCC/VSS	Power supply and ground	Operates over full USB VBUS range (4.0–5.25 V); no separate analog/digital supply needed.
VPP	EPROM programming voltage	Tied to ground during normal operation; only active during OTP programming - eliminates risk of accidental reprogramming.

Key Features

Feature	Design Value
USB SIE Hardware Acceleration	Offloads USB token, handshake, and data transfer handling - frees CPU for HID report generation and sensor polling.
Programmable I/O Sink Current	16-level per-pin current control on all 12 GPIOs - enables precise LED brightness tuning and noise-immune switch debouncing.
Instant-On Now™ Suspend Mode	Hardware-initiated low-power state with wake on USB activity, GPIO edge, or CEXT timeout - achieves <100 µA average current in mouse idle state.
Dual Stack Pointers (PSP/DSP)	Separate program and data stack pointers prevent USB FIFO corruption during nested interrupts - ensures reliable HID report transmission under load.
Security Fuse Bit	One-time programmable lock preventing EPROM readback - protects firmware IP in production HID peripherals.

Equivalent & Alternatives

The following parts are listed as comparable options for similar USB HID microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AN1083 (Microchip)	8-bit PIC16F with external USB transceiver; requires 3.3 V LDO and external 48-MHz crystal; no integrated SIE.	Higher component count and layout complexity; supports full-speed USB with additional firmware overhead.	Select when full-speed USB or mixed-signal ADC integration is required; not drop-in for CY7C63001C-PXC.
FTDI FT230X	USB-to-serial bridge IC; no MCU core or programmable memory; fixed HID-compliant CDC/ACM descriptors.	Limited to UART-based peripherals; cannot implement custom HID reports or sensor fusion logic.	Select for simple UART tunneling where host-side driver support is acceptable; lacks local processing capability.

Compared with AN1083 and FT230X, the CY7C63001C-PXC provides integrated USB SIE, OTP firmware storage, and configurable GPIO sink current - enabling fully self-contained HID devices with minimal external components and deterministic real-time response.

FAQ

What is the maximum sink current per GPIO pin on CY7C63001C-PXC?

Each P0.x and P1.x pin supports programmable sink current in 16 discrete levels, with maximum rated sink of 20 mA per pin for P1.x (high-current port) and 4 mA for P0.x (low-current port), as specified in Absolute Maximum Ratings. This allows direct LED driving on P1.x and robust switch interfacing on P0.x without external buffers.

Does CY7C63001C-PXC require an external crystal or can it use a ceramic resonator?

The CY7C63001C-PXC is designed exclusively for a 6-MHz ceramic resonator connected between XTALIN and XTALOUT pins. It does not support quartz crystals or external clock sources. The internal clock doubler generates the required 12-MHz core clock, eliminating need for higher-frequency components.

How is USB device enumeration handled without external pull-up resistors?

A 1.5 kΩ pull-up resistor must be connected from D– to VCC to signal low-speed USB device attachment. The CY7C63001C-PXC contains no internal pull-up; this external resistor is mandatory for host detection and address assignment. D+ remains unconnected to the pull-up to maintain low-speed signaling integrity.

Can the CY7C63001C-PXC operate from USB VBUS without additional regulation?

Yes - the device operates over 4.0 V to 5.25 V, fully covering USB 2.0 VBUS tolerance (4.4–5.25 V). No external regulator is needed; VCC connects directly to VBUS. Internal POR circuitry ensures reliable startup across this range, and the wide voltage window simplifies power design in bus-powered HID devices.
