What is the 5CSXFC6C6U23I7LN?

The 5CSXFC6C6U23I7LN is a Cyclone V SX System-on-Chip FPGA from Altera (Intel) that integrates 110K logic elements with a dual-core ARM Cortex-A9 hard processor system in a 672-UBGA package, sized 23x23 mm. It is the 5CSXFC6C6 family member with the -I7 industrial speed grade, where 'LN' indicates lead-free packaging. According to the Cyclone V device datasheet, it is positioned for low-power embedded designs requiring a Linux-capable host CPU plus deterministic FPGA acceleration.

What is the logic element count of 5CSXFC6C6U23I7LN?

The 5CSXFC6C6U23I7LN contains 110K logic elements as confirmed on the DigiKey product listing and the Altera product page. The Cyclone V SX family scales from approximately 25K up to 110K logic elements across the 5CSXC2/4/5/6 variants. 110K LE places the device in the mid-density segment of the family, suitable for moderate-complexity logic and DSP pipelines.

What is the HPS clock frequency of 5CSXFC6C6U23I7LN?

The hard processor system in the 5CSXFC6C6U23I7LN operates at up to 925 MHz, according to the DigiKey listing. The dual ARM Cortex-A9 MPCore subsystem uses this clock for the application cores, NEON media engine, single/double-precision FPU, and CoreSight debug. The FPGA fabric runs at a separate fabric clock; together they let Linux software offload compute to FPGA fabric accelerators.

What is the difference between 5CSXFC6C6U23I7LN and 5CSXFC6C6U23C8N?

The 5CSXFC6C6U23I7LN is the -I7 speed grade with industrial -40C to 100C temperature range, while the 5CSXFC6C6U23C8N is the -C8 commercial speed grade (slower fabric timing, 0C to 85C). Both share the same 5CSXFC6C6 die and 672-UBGA package, so they are pin-compatible. Choose -I7 for harsh-environment designs and -C8 when cost dominates and commercial temperature is acceptable.

Is 5CSXFC6C6U23I7LN a drop-in replacement for 5CSXFC6C6U23C7N?

Yes, the 5CSXFC6C6U23I7LN is a drop-in replacement for the 5CSXFC6C6U23C7N, with both parts sharing the 5CSXFC6C6 die and 672-UBGA (23x23) package footprint. The key difference is temperature grade and speed: the -I7LN is industrial temperature with the -7 fabric speed grade, while the -C7N is commercial temperature at the -7 speed grade. Parametric proximity is high (>90%); substituting -I7LN for -C7N gives wider temperature margin with identical pinout.

What is the price of 5CSXFC6C6U23I7LN?

As of 2026-09-06, the 5CSXFC6C6U23I7LN lists at $180.24 per unit on LCSC Electronics at qty 1, with tiered pricing down to roughly $119.55 at qty 1000. Distributor stock varies; DigiKey and Mouser both list the part with current stock.

The 5CSXFC6C6U23I7LN ships in a 672-pin Ultra FineLine BGA (UBGA) package measuring 23x23 mm, with a 0.8 mm ball pitch. This is the same package used across the 5CSXFC6 family including the -C8N, -C7N, -C6N, and -A7N speed grades. The UBGA footprint requires controlled-impedance PCB design and X-ray inspection post-reflow.

5CSXFC6C6U23I7LN vs 5CSXFC5C6U23I7N - which is better for motor control?

The 5CSXFC6C6U23I7LN is the better choice for motor control designs that need maximum FPGA fabric density and full HPS peripheral set - the 110K logic element budget gives room for encoder decode, PWM modulation, and field-oriented control state machines. The 5CSXFC5C6U23I7N (85K LE) is acceptable for lower-complexity motor tasks, with the same HPS and 672-UBGA package but smaller fabric. Both are pin-compatible and in the same Cyclone V SX family.

When should I choose 5CSXFC6C6U23I7LN over 5CSEBA6U23I7N?

The 5CSXFC6C6U23I7LN is the right choice when you need integrated transceivers plus a 110K LE fabric, which the 5CSEBA6U23I7N (Cyclone V SE, 110K LE) does not have. The SX family adds transceiver channels to the SE base, making SX better for designs with multi-gigabit serial links, camera interfaces, or chip-to-chip backplane communication. Both share the dual ARM Cortex-A9 HPS and 672-UBGA package.

What is the best drop-in replacement for 5CSXFC6C6U23I7LN?

The best drop-in replacement for the 5CSXFC6C6U23I7LN is the 5CSXFC6C6U23I7N (without the LN suffix), which shares the same 5CSXFC6C6 die, 672-UBGA package, and -I7 industrial speed grade. The only difference is the LN lead-free finish designation, which is functionally identical for non-automotive designs. Both are manufactured by Altera and are listed on the XAIPART Site MPN list.

What is the equivalent Altera part for 5CSXFC6C6U23I7LN from another brand?

Cross-brand SoC FPGA equivalents to the 5CSXFC6C6U23I7LN in the 28 nm low-power class include Xilinx Zynq-7000 family devices such as XC7Z020 and XC7Z030, which integrate dual ARM Cortex-A9 with FPGA fabric. The Zynq parts use a different package and pinout, so a PCB redesign is required. For a true drop-in cross-brand option, the XAIPART database and Octopart cross-reference tools should be consulted, as no same-package drop-in exists in current production.

Where to download 5CSXFC6C6U23I7LN datasheet PDF?

The official Altera/Intel Cyclone V device datasheet (covering all 5CSXFC6 family members including 5CSXFC6C6U23I7LN) is available from the Altera product page at https://www.altera.com/products/fpga/cyclone/v/sx/5csxc6-u23/5CSXFC6C6U23I7LN.

Design Notes

The 672-UBGA package uses 0.8 mm ball pitch and requires a 23x23 mm PCB land pattern with via-in-pad or dog-bone fanout. Use a minimum 4-layer stackup with dedicated GND and 0.85V/1.1V/2.5V/3.3V power planes; place bulk decoupling (10uF ceramic per rail) within 5 mm of the BGA balls and high-frequency 0.1uF + 1nF capacitors adjacent to each power ball group. The Cyclone V device datasheet pin tables list per-bank power rail requirements, and Quartus Prime Early Power Estimator must be run before final stackup commit.

Estimated: at full HPS utilization (925 MHz dual core) plus 80% FPGA fabric utilization, the 5CSXFC6C6U23I7LN dissipates approximately 5-8 W depending on toggle rate. The 672-UBGA package has theta_JB of approximately 4 C/W per Altera thermal models; without airflow, junction-to-ambient thermal resistance reaches 15-20 C/W depending on PCB copper. For sustained >5 W operation, attach a heatsink via thermal interface material to the package top, or use a 4 oz copper innerlayer with thermal via array under the BGA thermal balls.

The HPS boot configuration must be set up in Quartus Prime Platform Designer before bitstream generation - failing to lock pin mux assignments (NAND/NOR/SD/eMMC, USB PHY modes, Ethernet PHY interface) results in HPS boot failure that mimics silicon damage. The 5CSXFC6C6U23I7LN requires separate power sequencing: 3.3V must ramp before 2.5V, which must ramp before 1.1V, which must ramp before 0.85V - a violation triggers inrush currents that can collapse the HPS core supply. Use the Altera Enpirion power solution reference designs to avoid sequencing violations.
