Renesas 7006L20JGI

Overview

IDT7006L20JGI from Integrated Device Technology (IDT) is a high-speed 16K × 8 dual-port static RAM with true independent left/right port access, 20 ns maximum read cycle time (tRC), industrial temperature range (–40°C to +85°C), and low-power active/standby operation (700 mW typ. / 1 mW typ.). It enables real-time inter-processor communication in embedded control systems requiring deterministic memory arbitration.

For engineers reviewing the IDT7006L20JGI datasheet, IDT7006L20JGI pinout, IDT7006L20JGI application, or IDT7006L20JGI equivalent, key selection criteria include BUSY-flag arbitration timing (tBDD ≤ 30 ns), semaphore support for resource locking, battery backup data retention at 2 V, TTL-compatible 5 V ±10% supply, and 64-pin TQFP package compatibility with space-constrained industrial PCB layouts.

Technical Context

The IDT7006L20JGI implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port, enabling simultaneous read/write operations-even to the same memory location-via on-chip hardware arbitration logic. Its MASTER/SLAVE configuration (M/S pin) supports cascaded 16-bit+ word expansion without external logic.

It integrates full semaphore signaling (8 flags, addressed via A0–A2), interrupt flag generation (INTL/INTR), and BUSY flag assertion (BUSYL/BUSYR) with priority resolution governed by tAPS ≥ 5 ns setup time. The device operates in battery backup mode with V_CC = 2 V, retaining data while drawing ≤ 4 mA ICCDR (max) across military/industrial grades.

FAQ

What is the maximum operating temperature range supported by the IDT7006L20JGI?

The IDT7006L20JGI is rated for industrial temperature operation from –40°C to +85°C. This specification is validated per the datasheet's "Maximum Operating Temperature and Supply Voltage" table and applies to all AC/DC electrical characteristics at 20 ns speed grade. The device uses CMOS process technology optimized for thermal stability across this range, with no derating required up to +85°C ambient.

Does the IDT7006L20JGI support battery backup operation, and what voltage is required?

Yes, the IDT7006L20JGI supports battery backup operation with a minimum V_CC of 2.0 V for data retention, as specified in the "Data Retention Characteristics" table. At this voltage, the device retains stored data while drawing ≤ 4 mA (max) ICCDR current. The L-suffix denotes low-power design optimized for this mode, distinguishing it from the S-version which lacks guaranteed 2 V retention.

How does the BUSY flag arbitration work on the IDT7006L20JGI, and what timing parameters govern it?

The IDT7006L20JGI uses hardware BUSY flag arbitration where the M/S pin configures one port as Master (BUSY output) and the other as Slave (BUSY input). When contention occurs, the Master asserts BUSY to block the Slave's write until resolution. Key timing parameters include tAPS ≥ 5 ns (priority setup), tBDD ≤ 30 ns (disable-to-valid-data delay), and tWH ≥ 15 ns (write hold after BUSY), all verified at 20 ns speed grade per AC Electrical Characteristics tables.

Can the IDT7006L20JGI be used in a 16-bit data bus configuration, and how is that achieved?

Yes, the IDT7006L20JGI supports 16-bit expansion via MASTER/SLAVE cascading. Two devices are connected with M/S = H on the Master (BUSY output) and M/S = L on the Slave (BUSY input), sharing address and control lines while interleaving I/O0–I/O7 to form a 16-bit bus. This eliminates external glue logic and maintains full 20 ns speed, as confirmed in the "Description" section and functional block diagram.

What package type is used for the IDT7006L20JGI, and are there any layout considerations?

The IDT7006L20JGI uses a 64-pin Thin Quad Flatpack (TQFP) with 14 mm × 14 mm body and 0.5 mm pitch. Layout considerations include connecting all four VCC and six GND pins to low-impedance planes, placing 0.1 µF ceramic decoupling capacitors within 5 mm of each VCC pin, and routing address/control lines as matched-length pairs to minimize skew-per the "Pin Configurations" diagrams and recommended PCB guidelines in the datasheet.
