LCMXO3D-4300HC-5SG72C 概要

The Lattice Semiconductor LCMXO3D-4300HC-5SG72C is a non-volatile, low-power MachXO3D Field Programmable Gate Array (FPGA) offering 4300 Look-Up Tables (LUTs), 94208 bits of embedded Block RAM (EBR), and 58 user I/O in a 72-pin VFQFN exposed-pad package (SG72, 10x10 mm).

A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and embedded memory blocks that the user can configure post-manufacturing to implement arbitrary digital logic functions. Within the broader product hierarchy, an FPGA sits below the Application-Specific Integrated Circuit (ASIC) category but above fixed-function microcontrollers: it occupies the same role as a CPLD (Complex Programmable Logic Device) when logic density is small, but offers deeper memory, more I/O, and finer-grained routing. MachXO3D devices specifically target secure-control and instant-on glue-logic applications, extending the MachXO3 family with hardware Root-of-Trust, immutable security, and pre-verified cryptographic primitives.

Key features of the LCMXO3D-4300HC-5SG72C include 4300 LUTs (2150 Adaptive Logic Modules per Lattice datasheet), 94208 bits of EBR (about 11.8 kbytes), 96 kbits of distributed RAM, dedicated on-chip Flash Configuration Memory for instant-on behavior without external boot Flash, a Security Block supporting AES-256, SHA-256, HMAC, and ECDSA, and support for 2.5V/3.3V VCCIO with internal VCC core at 2.5V-3.3V. The device supports common interfaces such as I2C, SPI, I2S, UART, and LVDS via on-chip hardened IP. Operating junction temperature ranges from 0C to +85C (commercial grade, suffix 'C').

Architecturally, the MachXO3D HC variant uses a non-volatile configuration cell that eliminates external boot PROM and provides deterministic wake-up in under 1 ms, while the embedded Security Block isolates keys in tamper-resistant storage. Hardened I/O buffers tolerate 1.2V-3.3V signaling on independent banks, simplifying mixed-voltage board designs.

Typical applications for the LCMXO3D-4300HC-5SG72C include secure IoT endpoint controllers (hardware Root-of-Trust), industrial control bridging (SPI-to-I2C, I2C-to-UART glue logic), consumer device secure boot and firmware verification, automotive infotainment and ADAS glue logic in 4300 LUT class designs, and portable/wearable always-on sensor hubs.

When designing with this device, plan decoupling: place a 0.1 uF plus 1 uF ceramic within 5 mm of each VCC/VCCIO pin and bond the exposed pad (EP) directly to a ground plane with at least 9 thermal vias. Designers should evaluate whether the 58 available user I/Os (after package pad-out) meet their pin-count budget before committing to this variant.

設計ノート

MachXO3D HC devices require 2.5V or 3.3V on VCC, with separate VCCIO pins supporting 1.2V to 3.3V per I/O bank. Place 0.1 uF X7R ceramic decoupling within 3 mm of each VCC/VCCIO pin, plus a single 10 uF bulk capacitor near the package. The exposed pad (EP) must be soldered directly to a ground plane with at least 9 thermal vias (0.3 mm drill, 0.5 mm pitch) for thermal dissipation and electrical ground return - this is critical for non-volatile Flash configuration reliability.

Route all 58 user I/Os as 50 ohm controlled-impedance traces if any LVDS or SPI >50 MHz signals are used; otherwise standard 50 ohm microstrip is sufficient. Keep JTAG (TDI/TDO/TMS/TCK) traces short (under 50 mm) and isolated from switching supplies. Place the ProgramN pin with a 10 kohm pull-up to VCCIO0 to ensure clean configuration defaults at power-up.

Estimated: a design that uses more than 4300 LUTs will fail to fit the device silently at compile time. Compile with Lattice Diamond and review the 'Resource Usage' report to confirm utilization stays under 80 percent to leave routing headroom. Also verify that the chosen security profile (development vs production) is correct - locking the device in production mode is irreversible and prevents further JTAG access.

For LVDS pairs on the LCMXO3D-4300HC-5SG72C, match trace lengths to within 0.5 mm and use 100 ohm differential impedance. The part supports up to 8 LVDS pairs per bank; consult the MachXO3D datasheet pinout for exact pin assignments. Add a 100 ohm termination resistor across the differential pair at the receiver end when traces exceed 25 mm to avoid reflections.

Although the MachXO3D family is known for low power, the Security Block operations (AES-256, ECDSA) draw measurable current during boot. Estimated: peak supply current during Security Block stress can reach ~50 mA on VCC, producing 0.15 W dissipation at 3.3V; with theta JA around 30 C/W, junction rise is approximately 4.5 C - well within the 0C-85C commercial envelope, but adequate copper pour is required if used in enclosed industrial enclosures.
