Renesas 7200L15SOGI8

Overview

IDT7200L15SOGI8 from Renesas Electronics (formerly IDT) is a 256 x 9-bit asynchronous CMOS FIFO memory IC used for rate buffering and data synchronization between mismatched clock domains or bus protocols. It features 15 ns access time, ultra-low active power (440 mW max), full/half-full/empty status flags, and auto-retransmit capability. It is deployed in industrial communications interfaces requiring deterministic latency and overflow/underflow protection.

For engineers reviewing the IDT7200L15SOGI8 datasheet, IDT7200L15SOGI8 pinout, IDT7200L15SOGI8 application, or IDT7200L15SOGI8 equivalent, key selection criteria include its 256-word depth, 9-bit data width with parity support, 5 V single-supply operation, industrial temperature range (–40°C to +85°C), and compatibility with depth/width expansion architectures.

Technical Context

The IDT7200L15SOGI8 implements a dual-port ring-buffer architecture with independent read/write pointers managed entirely internally-no address lines required. It operates asynchronously: write and read cycles are triggered on falling edges of W and R inputs, respectively, with no shared clock dependency.

Its flag logic generates EF (Empty), FF (Full), and XO/HF (Half-Full or Expansion Out) outputs based on pointer arithmetic. The FL/RT pin serves dual roles: First Load in depth expansion mode or Retransmit enable in single-device mode, resetting the read pointer without affecting the write pointer.

FAQ

What is the operating voltage range for IDT7200L15SOGI8?

IDT7200L15SOGI8 operates from 4.5 V to 5.5 V DC. This 5 V nominal range ensures compatibility with standard TTL and CMOS logic families. Operation outside this range may cause functional failure or accelerated wear. The device draws up to 80 mA active current at VCC = 5 V, so proper decoupling and thermal design are essential.

Does IDT7200L15SOGI8 support parity checking?

Yes, IDT7200L15SOGI8 supports parity via its 9-bit data path: D0–D7 carry user data and D8 can be assigned as a parity bit. This configuration is commonly used in serial communication protocols like HDLC or custom industrial framing where error detection is required before processing. The FIFO itself does not generate or verify parity - it preserves the bit as part of the stored word.

Can IDT7200L15SOGI8 be used in depth expansion mode?

Yes, IDT7200L15SOGI8 supports depth expansion by cascading multiple units using XI and XO pins. In this mode, FL/RT configures the first device, and XO of each unit connects to XI of the next. Note that HF and RT functions are disabled in depth expansion, and composite EF/FF must be generated externally using OR logic across all devices.

What is the meaning of "SOGI8" in IDT7200L15SOGI8?

"SOGI8" denotes the package and environmental specification: SO = SOIC (28-pin), G = Green (Pb-free), I = Industrial temperature range (–40°C to +85°C), and 8 = tube packaging. This suffix confirms the device is RoHS-compliant, rated for industrial use, and supplied in bulk tubes - not tape-and-reel.

Is IDT7200L15SOGI8 still in production?

IDT7200L15SOGI8 is discontinued per Renesas PDN# SP-17-02, with last-time-buy expired June 15, 2018. However, Aetrix Electronics maintains verified legacy stock with full traceability and extended lifecycle support, including obsolescence mitigation planning and cross-reference guidance for migration paths.
