[edit] TLCS-47 Family

The microcontrollers in the TLCS-47 family are 4-bit systems.

[edit] TLCS-870 Family

The microcontrollers in the TLCS-870 family use a 8-bit/16-bit architecture reminiscent of the Z80.

[edit] TLCS-900 Family

The microcontrollers in the TLCS-900 family are 16-bit (TLCS-900, TLCS-900/L, TLCS-900/H and TLCS-900/L1 series) and 32-bit (TLCS-900/H1 series) systems. Most of them are CISC based, with a few systems being RISC based.

[edit] Features and differences

Current TLCS' offer some or all of the following features:

• multifunction, bi-directional general purpose I/O ports with optional built-in pull-up resistors
• mask programmable, one time programmable, flash memory or EEPROM type of ROM. ROMless versions are also available
• a variety of serial interfaces:
  • I²C
  • Synchronous/Asynchronous Serial Peripherals (UART/USART) (used with RS-232, RS-485, and more)
  • Serial Peripheral Interface Bus (SPI)
  • USB
• watchdog timer (WDT)
• multiplexed 10-bit A/D converters; D/A converters
• dual clock inputs and on-line clock switching by selecting different gear values (frequency divider), thus allowing either low-power low-frequency modes or high-performance high-frequency modes
• prescalable 8-bit and 16-bit timers (may be used as Programmable Interval Timers)
• 8-bit and 16-bit pulse-width modulation (PWM) and programmable pulse generation (PPG) output
• power voltage supply range between 1.8 to 5.5 Volt
• external interrupt control
• pattern generator, suitable for stepper motor control
• Chip select/wait controller
• different chip carrier formats

As demand for these features differs widely depending on the requirements for a specific project (low energy consumption; high number of I/O ports; etc.), customers can choose from a wide range of different versions.

[edit] Development Tools

Toshiba offers a ANSI C compatible C compiler and an assembler. Neither tool is available for free.

There is a project for porting GNU assembler to the TLCS-900 family.
