Product details
Overview
TUSB5152PZ from Texas Instruments is a USB 1.1-compliant 5-port hub controller with dual enhanced UARTs and IEEE-1284 parallel port interface, integrated 8052 MCU (16KB loadable RAM, 6KB ROM), 5-channel DMA, and PLL-based clock generation from 6-MHz crystal. It operates at 3.3 V or 5 V and supports full-speed (12 Mbps) USB data transfer in industrial serial/parallel peripheral bridging applications.
For engineers reviewing the TUSB5152PZ datasheet, TUSB5152PZ pinout, TUSB5152PZ application, or TUSB5152PZ equivalent, key selection criteria include its 100-pin TQFP package, dual UART flow control (Xon/Xoff, auto-RTS/CTS), RS485 transceiver support, EPP/ECP parallel mode with DMA, and integrated I²C master for external device configuration.
Technical Context
The TUSB5152PZ implements a fully autonomous USB 1.1 hub with one upstream and five downstream ports, managed by an embedded 8052 microcontroller running firmware loaded via USB or I²C. Its USB Serial Interface Engine (SIE) handles protocol compliance, while the UBM (USB Buffer Manager) coordinates endpoint buffers across eight IN and eight OUT endpoints.
Dual enhanced UARTs support programmable baud rates (50–460.8 kbps), 5–8-bit word length, parity, stop bits, and hardware/software flow control-including automatic RS485 direction control with and without echo. The IEEE-1284 port supports SPP, EPP, and ECP modes with DMA-assisted bulk transfers and direct Centronics printer interfacing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB bridge controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FT4232H | Quad UART + USB 2.0 Hi-Speed (480 Mbps); no parallel port; no integrated MCU; uses external EEPROM for configuration. | Better suited for high-bandwidth serial-only applications; lacks native parallel interface and firmware-execution capability. | Select FT4232H when USB 2.0 speed and four UARTs are required, and parallel connectivity is unnecessary. |
| CH341T | Single UART + parallel port + I²C; USB 2.0 Full-Speed only; no hub functionality; minimal MCU resources (no user-accessible RAM/ROM). | Targeted at cost-sensitive single-peripheral adapters; cannot support multi-port expansion or complex firmware-defined behavior. | Choose CH341T for simple USB-to-serial/parallel dongles where hub topology and field-upgradable firmware are not needed. |
Compared with FT4232H and CH341T, the TUSB5152PZ uniquely integrates a programmable 8052 MCU, 5-port USB hub, dual UARTs with RS485 control, and IEEE-1284 parallel support - enabling consolidated peripheral bridging without external controllers or protocol translation firmware.

FAQ
What USB specification does the TUSB5152PZ comply with?
The TUSB5152PZ complies fully with the USB 1.1 specification, supporting 12-Mbps full-speed data transfer. It implements all required descriptors, enumeration sequences, and error-handling behaviors defined in the USB 1.1 standard, ensuring interoperability with Windows, Linux, and macOS hosts without custom drivers. The TUSB5152PZ does not support USB 2.0 or later specifications.
Does the TUSB5152PZ support RS485 transceiver control?
Yes, the TUSB5152PZ provides hardware-assisted RS485 direction control on both UART channels. Its auto-RTS feature asserts the RTS signal synchronously with transmit start and deasserts it after the final stop bit, eliminating software timing dependencies. This ensures reliable half-duplex bus arbitration and is confirmed in Section 2.2 and Figure 7–3 of the TUSB5152PZ datasheet.
Can the TUSB5152PZ operate with both 3.3-V and 5-V supplies?
Yes, the TUSB5152PZ supports dual-supply operation: VCC = 3.3 V ±5% powers core logic and USB transceivers, while VCCS = 5 V powers parallel port drivers and certain I/O buffers. This separation allows direct interfacing with 5-V parallel peripherals and 3.3-V system logic without level shifters, as specified in Section 11.2 of the TUSB5152PZ datasheet.
How many USB endpoints does the TUSB5152PZ support?
The TUSB5152PZ supports up to eight input (IN) endpoints and eight output (OUT) endpoints, allocated across its five downstream ports and upstream connection. Endpoint configuration is managed dynamically by the internal 8052 MCU firmware using the Endpoint Descriptor Block (EDB) structure documented in Section 4.3 of the TUSB5152PZ datasheet.
Is external memory required to run the TUSB5152PZ firmware?
No, the TUSB5152PZ contains 6 KB of on-chip ROM with a USB/I²C boot loader and 16 KB of on-chip RAM that is fully loadable from the host during enumeration. Firmware execution occurs entirely within this internal memory space; no external Flash or RAM is required for basic operation, though optional external EEPROM may be used for persistent configuration storage via the I²C interface.
