AT75C310-Q160

The AT75C310-Q160 is a Smart Internet Appliance Processor (SIAP) based on an ARM7TDMI 32‑bit core running at 40 MHz, delivered in a 160‑lead PQFP (28×28 mm) surface‑mount package. The device combines a general‑purpose ARM7TDMI processor with dual OakDSP fixed‑point co‑processors and integrated memory and peripheral controllers to address embedded Internet appliance and VoIP use cases.

Designed for Internet telephony and networked appliance applications, the AT75C310-Q160 focuses on integration and system‑level performance: multiple processing engines, on‑chip boot ROM and fast RAM for DSP subsystems, and a flexible external bus and DRAM controller to support system memory and peripheral expansion.

Key Features

• Core ARM7TDMI 32‑bit microprocessor core operating at 40 MHz for system control and protocol processing.
• DSP Subsystem Two 16‑bit fixed‑point OakDSPCore® co‑processors provide dedicated signal processing capability and include 88 KB of integrated fast RAM for each DSP.
• Boot and Memory 256 × 32‑bit boot ROM plus on‑chip RAM for the DSPs; on‑chip DRAM controller and a flexible external bus interface with programmable chip selects for system memory expansion.
• Interfaces Dual codec interface, Industry‑standard SPI, two USARTs with FIFO and modem control lines, and up to 23 general‑purpose I/O pins for peripheral connectivity.
• Timers and System Multi‑level, individually maskable vectored interrupt controller, three 16‑bit timers/counters and an additional watchdog timer for system reliability and real‑time control.
• Debug and Development JTAG debug interface and available software development suites for ARM7TDMI and OakDSPCore development, plus ready‑to‑use application software modules.
• Package and Power 160‑lead PQFP (28×28) surface‑mount package with 3.3 V I/O and RoHS compliance.

Typical Applications

• VoIP Phones and Internet Telephony Dedicated DSP cores and integrated codec interfaces enable voice compression, echo cancellation and telephony signal processing while the ARM core handles protocol stacks and system control.
• Smart Internet Appliances Integrated boot ROM, DRAM controller and peripheral interfaces simplify the design of networked appliances that require protocol processing and media handling.
• Modems and Voice Processing Equipment Fixed‑point DSP engines and RAM per DSP make the device suitable for modem algorithms, voice codecs and other real‑time signal processing tasks.
• Embedded Networking Endpoints ARM control plus serial interfaces (SPI, USARTs) and GPIO support implementation of endpoint networking functions and device management.

Unique Advantages

• Heterogeneous processing ARM7TDMI general‑purpose core paired with two OakDSP fixed‑point cores allows workload partitioning between control and intensive signal processing tasks.
• Integrated DSP memory 88 KB of fast RAM per DSP minimizes external memory needs for real‑time algorithms and reduces system latency.
• System expansion flexibility On‑chip DRAM controller and a programmable external bus interface with chip selects provide scalable memory and peripheral options for varied system architectures.
• Rich peripheral set Dual codec interface, SPI, dual USARTs with FIFO and modem control lines and up to 23 GPIOs support diverse I/O and communication requirements.
• Development ecosystem JTAG debug support and available development suites for both ARM7TDMI and OakDSPCore accelerate bring‑up and reduce time‑to‑market.
• Manufacturing readiness 160‑lead PQFP surface mount packaging and RoHS compliance align with standard PCB assembly flows.
