Description

ST10R202-G1 is an electronic component model in the IC Chips product category. It features a high-performance 16-bit CPU with a CPU frequency of 0 to 50 MHz and a 40ns instruction cycle time at a 50-MHz CPU clock. The CPU has a multiply-accumulate unit (MAC), a 4-stage pipeline, and a register-based design with multiple variable register banks. It also has enhanced boolean bit manipulation facilities and additional instructions to support high-level languages (HLL) and operating systems. The on-chip special function register area has 1024 bytes, and the memory organization includes 1KByte on-chip RAM and up to 16 MBytes of linear address space for code and data. The external memory interface is programmable and supports different address ranges, with options for an 8-bit or 16-bit external data bus and multiplexed or demultiplexed external address/data buses. There are five programmable chip-select signals and support for hold and hold-acknowledge bus arbitration. The component also includes a one-channel PWM unit with fail-safe protection, a programmable watchdog timer, an oscillator watchdog, and an 8-channel interrupt-driven single-cycle data transfer facilities. It has timers with clock generation via on-chip PLL or direct/prescaled clock input, serial channels for synchronous/asynchronous communication, up to 77 general-purpose I/O lines, and electrical characteristics such as 5V tolerant I/Os and 5V fail-safe inputs. It operates at a power of 3.3 Volt +/-0.3V and has idle and power down modes. ST10R202-G1 is compatible with various support tools such as C-compilers, macro-assembler packages, emulators, evaluation boards, HLL-debuggers, simulators, logic analyzer disassemblers, and programming boards. It comes in a 100-Pin Thin Quad Flat Pack (TQFP) package.
