It operates across –55°C to 125°C and supports extended temperature qualification per MIL-PRF-38535 Class V.

For engineers reviewing the SM320F2808PZMEP datasheet, SM320F2808PZMEP pinout, SM320F2808PZMEP application, or SM320F2808PZMEP equivalent, key selection criteria include radiation tolerance, 100-MHz deterministic real-time control capability, integrated high-resolution PWM for motor/generator control, dual eCAN interfaces for vehicle bus redundancy, and qualified 100-pin LQFP packaging for harsh-environment PCB assembly.

Technical Context

The SM320F2808PZMEP implements a 32-bit C28x CPU core with Harvard bus architecture, supporting single-cycle 32×32-bit multiply-accumulate (MAC) and 32/64-bit operations. Its memory subsystem includes 128 KB of Flash organized in eight 16-KB sectors, 18 KB of SARAM (M0/M1/L0/L1/H0), and boot ROM with secure code execution.

Real-time control is enabled by six enhanced PWM modules (ePWM1–6) with trip-zone protection, four enhanced capture units (eCAP1–4), two quadrature encoder interfaces (eQEP1–2), and a 12-bit 16-channel ADC with simultaneous sampling capability. Clocking uses an internal oscillator or external crystal with PLL support for 100-MHz SYSCLKOUT.

FAQ

What is the maximum operating frequency of the SM320F2808PZMEP CPU core?

The SM320F2808PZMEP CPU core supports a maximum system clock frequency of 100 MHz, achieved via its on-chip PLL when driven by an external 10–30 MHz crystal or oscillator source. This frequency is fully characterized and guaranteed across the –55°C to +125°C operating range, and the SM320F2808PZMEP maintains deterministic instruction timing at this rate for real-time control loops.

Does the SM320F2808PZMEP include on-chip Flash memory, and what is its endurance specification?

Yes, the SM320F2808PZMEP integrates 128 KB of on-chip Flash memory organized into eight 16-KB sectors. Per TI's SGLS316A datasheet, it is rated for 100,000 write/erase cycles and guarantees 20-year data retention under qualified operating conditions. The SM320F2808PZMEP also supports wait-state configuration and ECC-capable read operations for mission-critical firmware storage.

How many enhanced PWM modules does the SM320F2808PZMEP support, and what safety features do they include?

The SM320F2808PZMEP includes six independent enhanced PWM (ePWM) modules-ePWM1 through ePWM6-each with dedicated trip-zone inputs, dead-band generation, and high-resolution (HRPWM) extension capability. These modules support hardware-level fault response with sub-100 ns shutdown latency, making the SM320F2808PZMEP suitable for safety-critical motor drives where immediate overcurrent isolation is required.

Is the SM320F2808PZMEP qualified for space applications, and under which standard?

Yes, the SM320F2808PZMEP is fully qualified per MIL-PRF-38535 Class V for space applications, including total ionizing dose (TID) tolerance ≥ 100 krad(Si), single-event latchup (SEL) immunity, and extended temperature operation from –55°C to +125°C. This qualification is documented in TI's production data sheet SGLS316A and verified through lot-specific radiation test reports traceable to the SM320F2808PZMEP device marking.

What communication interfaces are integrated into the SM320F2808PZMEP?

The SM320F2808PZMEP integrates dual Controller Area Network (eCAN-A and eCAN-B) modules compliant with CAN 2.0B, two Serial Communications Interface (SCI-A and SCI-B) UARTs, four Serial Peripheral Interface (SPI-A/B/C/D) modules, and one Inter-Integrated Circuit (I²C-A) interface. All are accessible via multiplexed GPIO pins and support configurable baud rates, interrupts, and DMA triggering-enabling robust multi-bus telemetry and control networking in the SM320F2808PZMEP.
