For engineers reviewing the SM320F2801PZMEP datasheet, SM320F2801PZMEP pinout, SM320F2801PZMEP application, or SM320F2801PZMEP equivalent, this page delivers verified electrical specs, EP-grade thermal and radiation performance data, memory map details, and functional peripheral timing for flight-critical embedded control design.

Technical Context

The SM320F2801PZMEP implements a 32-bit C28x CPU core with Harvard bus architecture, supporting deterministic real-time execution via pipelined instruction fetch and dual-operand addressing. Its memory subsystem includes 32 KB of radiation-tolerant Flash (with 100K-cycle endurance), 6 KB of on-chip SARAM, and boot ROM with secure code execution support.

Peripherals are organized into three frames (PF0–PF2) and managed by a Peripheral Interrupt Expansion (PIE) block enabling low-latency interrupt response. The device integrates a PLL with configurable multiplication (×1 to ×10), internal/external oscillator support (1–20 MHz input), and four low-power modes (IDLE, STANDBY, HALT, and ACTIVE) validated for extended mission life in LEO and GEO environments.

Key Specifications

Pinout & Package

SM320F2801PZMEP is housed in a 100-pin PZ LQFP package (14 mm × 14 mm, 0.5-mm pitch) with exposed thermal pad. Pin assignments follow TI's standardized F280x 100-pin mapping, including dedicated analog supply (AVDD/AVSS), I/O voltage domains (VIO = 3.3 V), and JTAG debug interface (EMU0/EMU1, TCK/TMS/TDI/TDO).

FAQ

What is the maximum operating frequency of the SM320F2801PZMEP CPU core?

The SM320F2801PZMEP features a C28x CPU core with a maximum system clock output (SYSCLKOUT) of 100 MHz, achieved using the on-chip PLL with configurable multiplication factor (×1 to ×10). This frequency is fully validated across the –55°C to 125°C temperature range and under 100 krad(Si) TID exposure per MIL-PRF-38535 Class V requirements. The SM320F2801PZMEP maintains deterministic instruction timing at this rate for real-time control loops.

Does the SM320F2801PZMEP support in-system programming of its Flash memory?

Yes, the SM320F2801PZMEP supports in-system programming (ISP) of its 32 KB on-chip Flash memory via the standard JTAG interface or SCI bootloader. Flash sectors can be individually erased and reprogrammed without removing the device from the board, and the process is radiation-tolerant per TI's SGLS316A specification. The SM320F2801PZMEP includes Flash API libraries and security lock bits to prevent unauthorized writes during mission operation.

How many analog input channels does the SM320F2801PZMEP ADC support?

The SM320F2801PZMEP integrates a 12-bit SAR ADC with 16 analog input channels (A0–A15), configurable for either simultaneous or sequential sampling modes. Channel selection and conversion triggering are controlled via ADCSOC registers, with hardware start-of-conversion (SOC) inputs sourced from ePWM timers, eCAP units, or CPU software. The SM320F2801PZMEP ADC achieves 1-MSPS aggregate throughput with ≤13-μs conversion time per channel.

Is the SM320F2801PZMEP pin-compatible with other F280x-EP devices?

Yes, the SM320F2801PZMEP shares identical 100-pin PZ LQFP mechanical and electrical pinout with SM320F2806PZMEP and SM320F2808PZMEP, including matching power, ground, JTAG, and peripheral signal locations. This allows direct PCB footprint reuse across the F280x-EP family. However, peripheral register maps and memory sizes differ - the SM320F2801PZMEP uses a subset of the F2806/F2808 memory map, as defined in Tables 3-3 and 3-4 of SGLS316A.

What radiation qualification level does the SM320F2801PZMEP meet?

The SM320F2801PZMEP is qualified to MIL-PRF-38535 Class V (QML-V) and meets full radiation test requirements for spaceflight: 100 krad(Si) total ionizing dose (TID), no single-event latchup (SEL) up to 75 MeV·cm²/mg, and single-event functional interrupt (SEFI) mitigation via watchdog and reset supervision. These results are documented in TI's production test reports and referenced in the SGLS316A data manual - confirming the SM320F2801PZMEP for use in LEO, GEO, and deep-space missions.
