The Toshiba TLCS series is a family of CISC and RISC microcontrollers from Toshiba.

Contents

TLCS-47 family

The microcontrollers in the TLCS-47 family are 4-bit systems. These are no longer advertised on the Toshiba web site.

TLCS-90 family

The microcontrollers in the TLCS-90 family use a 8-bit/16-bit architecture reminiscent of the Z80. These are no longer advertised on the Toshiba web site.

TLCS-870 family

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

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.

Features and differences

Current TLCS processors 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 and 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.

    Development tools

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

    The free Small Device C Compiler supports the TLCS-90.

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

    Alfred Arnold's The Macroassembler AS [1] is a free assembler supporting the TLCS-47, TLCS-870, TLCS-90, TLCS-900 and TLCS-9000 families.
