Obsolete TI DSPs
TMS320C6415
The TMS320C6415 is a C64x fixed-point DSP operating at up to 720MHz and 5760 MIPS. It includes PCI, McBSP, external memory interfaces and 1MB of L2 memory.
It remains in demand for legacy communications, imaging and multichannel signal-processing equipment.
SM320C6713B-EP
The SM320C6713B-EP is an enhanced-product floating-point DSP available in 200MHz and 300MHz speed grades. It provides audio-oriented interfaces, external memory support and an extended operating temperature range.
Common complete ordering codes include:
SM32C6713BGDPA20EP
SM32C6713BGDPS20EP
SM32C6713BGDPM30EP
The speed and temperature suffix must be checked before ordering.
Obsolete TI Microcontrollers
The TM4C1237D5PZ is an 80MHz Arm Cortex-M4F microcontroller with:
64KB Flash and 24KB SRAM
USB OTG, host and device support
CAN 2.0 interface
Two 12-bit ADC modules
100-pin LQFP package
−40°C to +85°C operation
Relevant ordering codes include TM4C1237D5PZI and TM4C1237D5PZIR. Firmware, Flash capacity, peripheral configuration and package compatibility should be reviewed before selecting an alternative.
Obsolete TI ADC and Audio Components
ADS5121
The ADS5121 is an 8-channel, 10-bit pipeline ADC with simultaneous sampling at up to 40MSPS. It uses a parallel CMOS output and a 257-ball, 16mm × 16mm BGA package.
The complete ordering code is ADS5121IZHK. It is used in legacy ultrasound, instrumentation and multichannel data-acquisition systems.
TLV320AIC23B
The TLV320AIC23B is a low-power stereo audio codec supporting sample rates from 8kHz to 96kHz. It integrates ADC, DAC and headphone-amplifier functions with I²S-compatible digital audio interfaces.
Common ordering codes include TLV320AIC23BIPW and TLV320AIC23BPW.
DRV8830 Lifecycle Status
The complete DRV8830 family is not obsolete. TI currently lists the main product family as active, but selected carrier options have been discontinued:
Obsolete PartActive Carrier OptionDifference
DRV8830DGQDRV8830DGQRTube versus large tape and reel
DRV8830DRCTDRV8830DRCRSmall versus large tape and reel
Customers should check the complete ordering code instead of treating all DRV8830 versions as discontinued.
Information Required for an RFQ
Please provide:
Complete TI part number
Required quantity
Package and speed grade
Temperature requirement
Acceptable date-code range
Destination country
Required inspection or traceability documents
Stock, pricing and lead time are confirmed for each inquiry.
Replacement and Compatibility Review
A newer TI component with similar specifications may not be a drop-in replacement. Before approving an alternative, compare:
Pinout and package dimensions
Supply and I/O voltages
Memory and processing performance
Peripheral interfaces
Firmware and development tools
ADC resolution or sample rate
Temperature and qualification grade
For maintenance projects, sourcing the original TI part number may avoid redesign and software migration costs.
FAQ
Are all the listed TI parts officially obsolete?
TMS320C6415, SM320C6713B-EP, TM4C1237D5PZ, ADS5121 and TLV320AIC23B are listed as obsolete by TI. Only specific DRV8830 carrier options are obsolete.
Are obsolete TI components available from stock?
Selected models may be available. Quantity, date code, condition and price must be confirmed by RFQ.
Why is the complete TI ordering code important?
The suffix can identify package, temperature range, speed grade and carrier format. Similar-looking part numbers may not be interchangeable.
Can you provide TI datasheets?
Yes. TI retains official product pages and datasheets for many discontinued parts. Datasheets should be reviewed before ordering or approving an alternative.
Can an active TI part directly replace an obsolete model?
Not always. Pinout, electrical characteristics, software and package compatibility must be verified before substitution.
