Product details

Overview

CY7C63413-PVC from Cypress Semiconductor is an 8-bit RISC OTP microcontroller with integrated USB 1.0 transceiver, 8 KB EPROM, 256 bytes RAM, 32 GPIO pins (24×7 mA + 8×12 mA sink), and 12-bit free-running timer - designed for low-speed HID devices including keyboards with integrated pointing, gamepads, and USB-to-PS/2 bridge applications.

For engineers reviewing the CY7C63413-PVC datasheet, CY7C63413-PVC pinout, CY7C63413-PVC application, or CY7C63413-PVC equivalent, this device delivers USB enumeration support, maskable GPIO interrupts, programmable I/O configurations (CMOS/open-drain/pull-up), and dual-mode (USB/PS/2) auto-configuration - critical for cost-sensitive embedded peripheral control.

Technical Context

This controller implements a Harvard-architecture RISC core running at 12 MHz internal clock (6 MHz external ceramic resonator), supporting USB 1.0 low-speed (1.5 Mbps) signaling with full endpoint management (1 address, 3 endpoints) and automatic bus enumeration. Its memory map includes dedicated I/O registers (0x00–0x08, 0x10–0x3F) for USB status/control, timer, DAC, and GPIO configuration.

The device integrates a 12-bit free-running timer with 1 µs resolution, watchdog reset (WDR), power-on reset (POR), and a DAC port (on CY7C635xx variants only) - but CY7C63413-PVC excludes DAC functionality and uses only standard GPIO ports 0–3. All 32 GPIOs support interrupt generation and configurable drive modes.

Key Specifications

Parameter	Value and Actual Design Meaning
USB Speed	Low-speed at 1.5 Mbps - compliant with USB 1.0 spec for HID-class peripherals; no external PHY required.
EPROM Size	8 Kbytes - stores firmware for USB descriptor handling, HID report processing, and GPIO logic in one-time programmable memory.
RAM Size	256 bytes - supports stack operations, endpoint buffer management, and real-time I/O state tracking.
GPIO Count & Drive	32 pins: Ports 0–2 (24 pins, 7 mA sink typical); Port 3 (8 pins, 12 mA sink typical) - enables direct LED driving without external drivers.
Timer Resolution	12-bit free-running timer with 1 µs tick - provides precise timing for debouncing, polling intervals, and USB SOF synchronization.
Supply Voltage	4.0 V to 5.5 V DC - compatible with standard TTL/CMOS logic rails and legacy PS/2 interface voltage levels.
Operating Temp	0 °C to +70 °C - rated for commercial-grade embedded peripheral operation without thermal derating.

Pinout & Package

Package: 40-pin Plastic DIP (PDIP), body width 0.600 inch, lead pitch 0.100 inch - suitable for through-hole prototyping and industrial PCB assembly.

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Power supply	Primary 4.0–5.5 V DC input; decoupling required at pin for USB noise immunity.
GND	Ground reference	Dedicated analog/digital ground return; must be low-impedance for stable USB signaling.
D+ / D−	USB differential data pair	Integrated transceiver I/O; requires 1.5 kΩ pull-up on D+ for low-speed device enumeration.
XTAL1 / XTAL2	Ceramic resonator interface	Drives 6 MHz external resonator; internal oscillator generates 12 MHz CPU clock.
P0.0–P0.7	Port 0 bidirectional I/O	8-bit GPIO bank with configurable pull-up/open-drain/CMOS; 7 mA sink capability.
P1.0–P1.7	Port 1 bidirectional I/O	8-bit GPIO bank identical to Port 0; supports individual interrupt enable via register 0x05h.
P2.0–P2.7	Port 2 bidirectional I/O	8-bit GPIO bank; used for auxiliary functions like PS/2 clock/data when in dual-mode.
P3.0–P3.7	Port 3 high-drive I/O	8-bit GPIO bank with 12 mA sink; directly drives LEDs or small solenoids without buffering.

Key Features

Feature	Design Value
USB/PS/2 Auto-Configuration	Detects host interface type at power-up and configures internal routing and protocol stack accordingly - eliminates manual mode selection jumpers.
Maskable GPIO Interrupts	All 32 I/O pins support individually enabled edge-triggered interrupts (rising/falling) - enables responsive key-scan or button wake-up without polling.
Configurable I/O Drive Modes	Each port supports CMOS output, open-drain, or input-with-pull-up via GPIO Configuration Register (0x08h) - simplifies interface to diverse peripherals (switches, LEDs, PS/2 lines).
On-chip USB Transceiver	Integrates differential receiver, transmitter, and line-state detection - removes need for external USB PHY IC and reduces BOM count by one component.
Watchdog & POR Circuitry	Dedicated WDR and POR blocks ensure deterministic startup and fault recovery - critical for unattended HID devices like kiosks or industrial consoles.

Applications

Use Scenario: Ruggedized front-panel interface for factory HMIs, medical devices, or building automation systems.

IC Role / Device Role / Timing Role: Embedded controller handling tactile feedback, LED indicators, and ESD-hardened switch inputs.

Use Value: 4.0–5.5 V operation tolerates brown-out conditions; 0–70 °C rating ensures reliability in non-climate-controlled environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar USB peripheral controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CY7C63412-PVC	6 KB EPROM (vs. 8 KB); identical GPIO, USB, and timer architecture.	Suitable where firmware size ≤6 KB; reduces mask cost for high-volume production.	Select when firmware footprint fits within 6 KB and cost optimization is prioritized over future firmware expansion headroom.
CY7C63513-PVC	Adds 8-pin DAC port with programmable current sinks (0–20 mA per pin); same 8 KB EPROM and GPIO count.	Enables analog output (e.g., PWM dimming, sensor calibration) alongside USB HID functions.	Choose when system requires analog actuation or precision current sourcing beyond GPIO capabilities.

Compared with CY7C63412-PVC, CY7C63413-PVC offers 2 KB more firmware space for complex HID descriptors or multi-language support; versus CY7C63513-PVC, it omits DAC functionality - reducing cost and complexity where analog outputs are unnecessary.

FAQ

Is CY7C63413-PVC pin-compatible with CY7C63412-PVC?

Yes - both share identical 40-pin PDIP package, GPIO mapping, USB interface pins (D+/D−), and register layout. Firmware compiled for CY7C63412-PVC runs unchanged on CY7C63413-PVC, though the latter supports larger code images due to its 8 KB EPROM.

Does CY7C63413-PVC require an external crystal?

No - it operates with a 6 MHz external ceramic resonator (not crystal), connected between XTAL1 and XTAL2. The internal oscillator multiplies this to 12 MHz for CPU execution; no load capacitors or crystal tuning network is needed.

Can CY7C63413-PVC drive LEDs directly without current-limiting resistors?

No - while Port 3 pins sink up to 12 mA typical, external current-limiting resistors are mandatory to prevent overcurrent and ensure consistent LED brightness across voltage and temperature variations per Cypress DC characteristics.

What USB descriptor types does CY7C63413-PVC support natively?

It supports standard USB 1.0 device, configuration, interface, endpoint, and HID descriptors via firmware - the hardware provides USB packet assembly/disassembly and endpoint FIFO management, but descriptor content is defined in EPROM-resident firmware.
