MAP1602 Overview
An SSD controller is a semiconductor system that coordinates a host interface, NAND media, firmware, cache management, error handling, and data-transfer paths. In the storage hierarchy, the MAP1602 is a storage controller, then an NVMe controller, then a PCIe interface controller, and finally a semiconductor used in solid-state storage. Its DRAMless architecture means external DRAM support is not identified in the supplied MAP1602 description; firmware and on-controller resources therefore carry greater responsibility for mapping and cache behavior.
The verified interface data supports PCIe Gen4 x4 connectivity and four NAND channels, each supporting up to four CE devices per channel. The related controller PDF also associates MAP1202-I and MAP1602-I families with DRAMless PCIe/NVMe designs, but the supplied snippets do not establish the exact package, pinout, operating voltage, NAND timing, ECC capability, endurance, power figures, or lifecycle status for MAP1602. Those parameters must be confirmed against the original manufacturer documentation before schematic release or production sourcing.
Typical design targets include M.2 NVMe SSDs, client notebooks, compact desktops, and other systems with a PCIe Gen4 x4 storage slot. The referenced SSD listing reports densities of 1TB and 2TB, sequential reads up to 7000MB/s, writes up to 6000MB/s, and a 3.3V ±5% supply condition for a module built around this controller; these are module-level claims, not guaranteed MAP1602 IC ratings.
PCB design should preserve the high-speed PCIe and NAND signal-integrity requirements, provide correct power sequencing, and follow the manufacturer’s reference layout and firmware requirements. Because the available evidence does not provide a complete pinout or electrical table, engineers should not infer package details from unrelated MAP1602 listings. The public datasheet URL supplied here is a retrieved PDF reference, while its manufacturer and revision metadata remain to be confirmed.
This page consolidates the verified interface capabilities, module-level SSD claims, architecture descriptions, and engineering limitations for MAP1602. It also distinguishes useful design context from unverified controller-level specifications so procurement and hardware teams can request the correct manufacturer package data before committing a design.

Typical Applications
MAP1602 is suitable for 6 applications: PCIe Gen4 M.2 NVMe SSD, High-Sequential-Throughput Client SSD, DRAMless Consumer Storage, Compact 22 x 80 mm Storage Module, Laptop and Desktop Storage Upgrade, High-Density NVMe SSD Platform.
PCIe Gen4 M.2 NVMe SSD
The MAP1602 fits a PCIe Gen4 x4 M.2 SSD because the verified controller description matches the host interface required by the reference module listing. A four-channel NAND interface supporting up to four CE devices per channel provides a path toward high-density flash configurations, while Smart Cache and multi-core Fusion technology are intended to improve resource utilization and transfer efficiency. The design must still be validated against the selected NAND’s timing, ECC, power, and thermal requirements.
Recommended
High-Sequential-Throughput Client SSD
The MAP1602 is suitable for a client SSD designed around sequential throughput when the target performance is close to the verified module claim of up to 7000MB/s read and 6000MB/s write. Those values depend on the complete SSD, not the controller alone, so engineers must qualify NAND type, firmware queue behavior, PCIe link width, thermals, and host benchmarking. The Gen4 x4 interface is the principal alignment between the controller and this application.
Recommended
DRAMless Consumer Storage
A DRAMless consumer SSD can use the MAP1602 family architecture when the firmware and NAND mapping strategy are designed for operation without an external DRAM cache. The supplied family PDF specifically associates MAP1602-I with DRAMless PCIe/NVMe controller technology and describes Smart Cache as a means of improving on-die resource utilization. Designers should validate power-loss behavior, write consistency, garbage collection, and supported flash profiles rather than assuming every MAP1602 orderable code has identical memory architecture.
Recommended
Compact 22 x 80 mm Storage Module
The MAP1602 aligns with a compact 22 x 80 mm M.2 module because the verified SSD listing identifies that form factor and reports dimensions of 22.00mm x 80.00mm x 3.50mm. The controller must be placed with adequate routing clearance for PCIe and NAND escape paths, while the power system must accommodate the module’s stated 3.3V ±5% supply condition. The module dimensions and supply figure are reference-product claims, not a substitute for controller package documentation.
Recommended
Laptop and Desktop Storage Upgrade
The MAP1602 can support a PCIe Gen4 x4 storage design intended for a notebook or desktop platform with an NVMe-capable M.2 slot. The supplied reference information lists Windows and Linux support at the SSD level, and the Gen4 x4 interface provides the appropriate host connection for high-bandwidth storage designs. Platform validation should still cover boot behavior, power states, thermal throttling, PCIe signal integrity, operating-system support, and the exact firmware profile.
Recommended
High-Density NVMe SSD Platform
The four-channel NAND interface and up-to-four-CE-device-per-channel statement make MAP1602 relevant to high-density NVMe SSD architecture studies. The available information does not identify supported NAND types, die organizations, ECC strength, or endurance ratings, so capacity planning cannot be finalized from the public snippets alone. A production design should qualify each NAND population, map-table limits, power-loss behavior, and sustained-write performance with the controller firmware.

Design Notes
Treat the PCIe Gen4 x4 host interface as a high-speed design problem. Follow the controller supplier’s reference layout, provide a continuous return path, minimize layer transitions, and validate differential routing with the intended board stackup. The supplied results do not provide pin assignments or trace-length guidance, so these details must come from the original Maxio design documentation rather than SSD-module marketing pages.
The reference SSD listing specifies a 3.3V ±5% module supply condition, but that is not a complete controller power tree. Confirm every controller, NAND, and auxiliary-supply rail against the original datasheet, including sequencing, current limits, ripple, decoupling, and brownout behavior. Do not copy the module-level 3.3V figure into the controller schematic without checking the exposed-pad and core-voltage requirements.
Validate sustained sequential read and write workloads because the reported 7000MB/s read and 6000MB/s write figures are module-level claims. Measure controller and NAND temperature in the completed M.2 module under the intended airflow and enclosure conditions. Confirm the controller package, thermal pad arrangement, and thermal limits before choosing copper area or a heatsink strategy; those package details are not present in the verified data.
Compliance Information
The supplied MAP1602 SSD listing and controller search results do not provide controller-level RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 status. Related MAP1602A assembly search results mention RoHS, but that does not establish compliance for the target MAP1602.
