LC4128ZE-7MN144C Tóm tắt

The Lattice Semiconductor LC4128ZE-7MN144C is a 128-macrocell ultra-low-power CPLD from the ispMACH 4000ZE family, housed in a 144-ball CSBGA (7x7 mm, 0.5 mm pitch) package. It features 96 user I/O, 8 logic blocks, a 7.5 ns pin-to-pin propagation delay (tpd), and a maximum internal operating frequency of 172 MHz. The device operates from a single 1.8 V core supply (1.7 V to 1.9 V) and is in-system programmable through a standard IEEE 1532 / JTAG interface.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like AND/OR arrays with a central switch matrix. CPLDs sit between discrete glue logic (74-series gates) and FPGAs in the programmable logic hierarchy: like discrete logic they boot instantly from on-chip flash, and like FPGAs they implement arbitrary combinatorial and sequential functions. The ispMACH 4000ZE family specifically targets battery-powered and portable applications where static and dynamic power consumption are critical.

Key differentiating features include Lattice's ultra-low-power 1.8 V architecture, per-pin slew-rate control, 3.3 V tolerant I/O with 5 V tolerant inputs, in-system programmability via JTAG, and a commercial operating temperature range of 0C to +90C (TJ). The CSBGA-144 package is footprint-compatible with the rest of the ispMACH 4000ZE family (64, 128, 256, and 512 macrocell densities in the same 144-ball outline where applicable), enabling designers to migrate density up or down without PCB rework.

Architecturally, each macrocell contains a programmable AND array feeding an OR array, a flip-flop, and a feedback path. Eight logic blocks are interconnected by a global routing pool, providing predictable, deterministic timing with zero-fanout delays independent of placement. This makes the LC4128ZE-7MN144C well suited to replace multiple 74LV logic chips with a single in-system reconfigurable device while preserving exact cycle-accurate behavior.

Typical applications include portable handheld and battery-powered consumer products, digital camera and camcorder glue logic, low-power instrumentation, LCD display timing controllers, and I2C/SPI/UART bus bridging/level shifting. The ultra-low static current also makes it attractive as a power-management sequencer in always-on subsystems of larger SoCs.

Designers should note that 96 I/O is the maximum user I/O count - the actual usable count depends on JTAG programming pin sharing. Always use Lattice's ispLEVER Classic or Lattice Diamond (with the ispMACH 4000ZE support files) for synthesis and fitting to guarantee timing closure. The CSBGA package requires careful PCB layout with microvia or via-in-pad technology to escape the 0.5 mm ball pitch.

Ứng dụng tiêu biểu

LC4128ZE-7MN144C phù hợp cho 6 Áp dụngs: Portable Handheld & Battery-Powered Devices, Digital Camera & Camcorder Glue Logic, Low-Power Instrumentation Front-End, I2C / SPI / UART Bus Bridging and Level Shifting, LCD Display Timing Controller, Power-Management Sequencer for Always-On Subsystems.

📱

Portable Handheld & Battery-Powered Devices

The LC4128ZE-7MN144C's 1.8 V ultra-low-power architecture targets portable handheld devices where battery life is critical - typical static current is on the order of microamps per macrocell, and dynamic current scales with frequency. The 96 user I/O at 0.5 mm CSBGA pitch fits the small PCB area of handheld form factors, while the 7.5 ns tpd and 172 MHz internal frequency handle button debouncing, LCD timing, and bus glue at low system clock rates. Placed as the central glue-logic hub between an application processor, an LCD controller, and several peripheral sensors, the CPLD replaces dozens of 74LV chips while extending battery life by 20-30% versus 3.3 V CPLDs. Unlike an FPGA, the CPLD boots instantly with no external configuration memory, eliminating the wake-up delay that handheld power-management designs must avoid.

Digital Camera & Camcorder Glue Logic

The LC4128ZE-7MN144C serves as the timing and bus-bridging hub in digital still cameras and camcorders, where it interfaces image sensors (typically MIPI or parallel CMOS), LCD panels, SD card controllers, and zoom/focus motors. The 128 macrocells handle multi-channel DMA timing, sensor sync pulse generation, and I2C/SPI multiplexing - tasks that consume 30-40 macrocells each. The 1.8 V core is ideal for direct interfacing to modern CMOS image sensors that operate from 1.8 V analog/digital supplies. Compared to discrete 74LVC logic, the CPLD saves approximately 60% PCB area and reduces quiescent current by 50%. JTAG in-system programmability allows field firmware updates for late-stage design changes without respinning the camera module.

Low-Power Instrumentation Front-End

The LC4128ZE-7MN144C is well suited as the digital control and timing core of low-power instrumentation - handheld oscilloscopes, portable multimeters, and bench-top data loggers - because the 1.8 V ultra-low-power supply allows the instrument to run for hundreds of hours on a single battery charge. The 96 user I/O drive LCD segments, rotary-encoder quadrature decoders, ADC trigger logic, and SPI-keypad scanners in parallel, tasks that consume 60-80 macrocells. The 7.5 ns tpd gives 133 MHz equivalent sample timing for trigger alignment, more than adequate for low-bandwidth instrumentation. The CSBGA-144 footprint fits the compact front-end PCB of portable meters, and the deterministic timing simplifies EMI compliance in CE/FCC-certified products.

I2C / SPI / UART Bus Bridging and Level Shifting

The LC4128ZE-7MN144C implements multi-protocol bus bridges between mixed-voltage domains - for example, translating between a 1.8 V application-processor I2C bus and a 3.3 V sensor SPI bus, with custom interrupt aggregation. The 96 user I/O provide enough ports for 4-6 simultaneous bus segments, and the 128 macrocells implement UART-to-SPI bridges, I2C address translators, and GPIO expanders in a single chip. The 5 V tolerant inputs on the I/O allow direct interfacing to legacy industrial 5 V peripherals without external level shifters, which saves 8-10 74LVC1T45 translators per board. The 7.5 ns tpd is fast enough for 400 kHz I2C Fast-Mode and 10 MHz SPI without timing violations.

LCD Display Timing Controller

The LC4128ZE-7MN144C functions as a dedicated timing controller for small TFT-LCD panels in embedded displays, generating HSYNC, VSYNC, DE, and pixel clocks at configurable resolutions up to 800x480 at 60 Hz. The 172 MHz maximum internal frequency supports pixel clocks for QVGA and WVGA panels, and the 128 macrocells fit a complete panel timing generator plus a backlight PWM controller plus a touch-panel I2C bridge. The CSBGA-144 footprint and 1.8 V operation allow the timing controller to be placed directly under the panel flex connector on the display side of the PCB. Compared to a microcontroller running bare-metal code, the deterministic CPLD timing eliminates jitter-induced pixel artifacts without RTOS or interrupt latency concerns.

Power-Management Sequencer for Always-On Subsystems

The LC4128ZE-7MN144C is ideal as a power-rail sequencer in always-on subsystems of larger systems - set-top boxes, network-attached storage (NAS), industrial controllers - where the CPLD controls enable timing for 8-12 voltage rails to a main SoC. The 96 user I/O drive each rail's enable pin, and 128 macrocells encode the sequencing state diagram plus fault detection logic. The 1.8 V ultra-low-power supply allows the CPLD itself to remain powered from a 1.8 V always-on rail, drawing less than 1 mA total. Unlike a discrete sequencer ASIC, the CPLD's JTAG interface allows late-stage sequencing changes without mask respins. The 7.5 ns tpd supports sub-millisecond rail ramp times for SoC power-on reset requirements.

The LC4128ZE-7MN144C is supported by Lattice Diamond (current generation) with the ispMACH 4000ZE device library, and by the legacy ispLEVER Classic toolchain. Both tools support VHDL, Verilog, and schematic-based design entry. Programming is performed via JTAG using Lattice's ispVM System or a compatible third-party tool like the Lattice HW-USBN-2A programmer cable.
What is the best cross-brand equivalent for LC4128ZE-7MN144C?
There is no exact cross-brand pin-compatible equivalent for the LC4128ZE-7MN144C - the ispMACH 4000ZE architecture and CSBGA-144 pinout are Lattice-specific. Competing ultra-low-power CPLDs from Xilinx (CoolRunner-II), Altera (MAX II Z), and Microchip (ATF1500) family use different packages and JTAG pinouts, so they require PCB rework. For cross-brand migration, contact Lattice FAE for the closest functional alternative in your application.
What are the key specifications of LC4128ZE-7MN144C that engineers should know?
The LC4128ZE-7MN144C has three headline specifications engineers always check: 128 macrocells in 8 logic blocks, 96 user I/O on a 144-ball CSBGA 7x7 mm package, 7.5 ns maximum tpd at 1.8 V nominal core supply (1.7-1.9 V range), and 172 MHz maximum internal frequency. The combination of 1.8 V operation, JTAG in-system programmability, and 96 I/O at 0.5 mm pitch is what makes this part unique in the 4000ZE family.

Hướng dẫn chọn lựa

Choose LC4128ZE-7MN144C when designing 1.8 V ultra-low-power portable or handheld products where 128 macrocells, 96 user I/O, and 7.5 ns tpd at the lowest unit price are required. Choose LC4128ZE-7MN144I if your product must operate in industrial temperature environments from -40C to +105C - same electrical specs, identical CSBGA-144 footprint, drop-in upgrade. Choose LC4128ZE-5MN144C if 7.5 ns tpd is too slow for your critical paths (e.g., 100 MHz+ memory bus interfaces) - the 5 ns grade is the same part with 33% faster propagation. Choose LC4256ZE-7MN144I or LC4256ZE-5MN144C if your design grows beyond 128 macrocells - both share the same CSBGA-144 footprint and can be a drop-in density upgrade without PCB rework.

Ghi chú thiết kế

The 144-CSBGA package uses a 0.5 mm ball pitch on a 7x7 mm body. PCB design requires microvia or via-in-pad technology for the inner balls to escape the BGA array - standard 0.3 mm through-hole vias will not fit between the balls. Use 4-layer stackup minimum with a continuous GND plane beneath the device for return-path integrity and thermal dissipation. The CSBGA thermal pad (central balls) must be soldered to a thermal copper pad on the PCB and tied to GND for electrical and thermal performance.

The LC4128ZE-7MN144C requires a clean 1.8 V core supply and per-bank VCCIO supplies. Place 0.1 uF and 10 uF ceramic bypass caps on each VCC and VCCIO pin within 2 mm of the package ball. Use a ferrite bead or Pi-filter between the system 1.8 V regulator and the CPLD's VCC pins to suppress switching noise from upstream DC-DC converters. Total quiescent current at 1.8 V is in the low milliamp range - budget at least 20 mA for the core plus another 5 mA per active I/O bank.

Do not exceed 3.3 V on VCCIO pins - although inputs are 5 V tolerant, VCCIO must stay within 1.3x its nominal value. Always reserve JTAG pins (TDI, TMS, TCK, TDO) as no-connects in user designs unless JTAG is being used - these balls are shared with the configuration engine. When migrating to LC4256ZE, verify timing closure because the higher-density device has slightly different fitter behavior at the same tpd grade.
